🔗 DOI🏠 PMC📚 PubMed📄 PDF
Agrocybe cylindracea, an edible and medicinal mushroom, comprises white (BC) and brown (CS) strains. The white strain is a new cultivar whose nutritional value remains unexplored. Nutritional components and bioactivities of BC and CS were compared using electronic nose, electronic tongue, texture analyzer, chromatography, taste re-addition experiments, and cytotoxicity assays. BC showed significantly higher crude polysaccharides, soluble protein, crude fiber, equivalent umami concentration, taste-active compounds (free amino acids and 5′-nucleotides), and stronger sourness, bitterness, sweetness, and umami than CS. Aspartic acid, glutamine, tryptophan, lysine, and 5′-cytidylic acid mainly contributed to sourness; glutamine and tryptophan to umami. Gas Chromatography-Mass Spectrometry (GC–MS) identified 41 (BC) and 37 (CS) volatiles with distinct aroma profiles. Both strains inhibited HCT116 and HGC27 proliferation via elevated reactive oxygen species (ROS). This first systematic comparison demonstrates BC exceeds CS in nutritional value, flavor, and anticancer activity.

🔗 DOI🏠 PMC📚 PubMed📄 PDF
SummaryMicroalgae-based technology is an effective and environmentally friendly method for antibiotics-contaminated wastewater treatment. To assess the tolerance and removal ability of Chlorella sorokiniana to ciprofloxacin (CIP), this study comprehensively revealed the responses of C. sorokiniana to CIP exposure and its degradation processes through physiological and transcriptomic analyses. Although the photosynthetic system was inhibited, the growth of C. sorokiniana was not negatively affected by CIP. Dissolved organic matter was analyzed and indicated that humic-like substances were released to alleviate the stress of CIP. In addition, the maximum removal of CIP was 83.3% under 20 mg L−1 CIP exposure. HPLC-MS/MS and RNA-Seq analyses suggested that CIP could be bioaccumulated and biodegraded by C. sorokiniana through the reactions of hydroxylation, demethylation, ring cleavage, oxidation, dehydrogenation, and decarboxylation with the help of intracellular oxidoreductases, especially cytochrome P450. Collectively, this research shows that C. sorokiniana have a great potential for removing CIP from wastewater.

🔗 DOI🏠 PMC📚 PubMed📄 PDF
A long extraction time for traditional cold coffee brewing considerably reduces the production efficiency of this type of beverage. Herein, a new ultrasound-assisted cold brewing (UAC) method was established. The feasibility of UAC was assessed by comparison with main physicochemical characteristics, non-volatile and volatile compounds in coffee extracts produced by hot brewing and conventional static cold brewing methods. Compared to the static cold brews, the levels of total dissolved solids, total lipids, proteins, and titrated acids of UAC coffee extracts increased by 6–26%, 10–21%, 26–31%, and 12–15%, respectively. Caffeine, chlorogenic acid, and trigonelline concentrations were also determined by HPLC. Based on the volatile profiles obtained by HS-SPME-GC/MS, the aroma compounds in UAC was significantly different (p < 0.05) from hot brews but similar to static cold ones, suggesting that ultrasonication compensated for the time of the static cold brewing, thereby considerably shortening the extraction time (1 h vs. 12 h). This work demonstrated that the combination of ultrasound-assisted with cold brew could produce coffee with good flavor and increase the extraction efficiency, which may provide an option for the acceleration of the cold brew coffee process.

🔧 Dépannage HPLC — arbre de décision 6 problèmes courants

Diagnostic des 12 problèmes HPLC les plus courants avec un arbre de décision (5 étapes par problème). Source : Snyder/Kirkland/Dolan 3rd ed. Chapter 17 + LCGC LC Troubleshooting columns 1989-2024.

Pics élargis (broad peaks) medium

Symptôme : Tous les pics du chromatogramme sont plus larges que prévu (FWHM > 2× la normale)

🔍 Arbre diagnostique :
  1. 1. Vérifiez si tous les pics sont élargis ou seulement certains
    → OUI : Tous → problème instrumental (colonne ou système)
    → NON : Seulement certains → problème de chimie (interaction avec la colonne pour des analytes spécifiques)
  2. 2. Remplacez par une colonne de test — le problème disparaît-il ?
    → OUI : COLONNE usée — garnissage endommagé, void dans les premiers mm. Remplacez-la.
    → NON : Problème dans le système LC
  3. 3. Vérifiez le volume mort (dead volume) — boucle d'injection, connexions, détecteur
    → OUI : Boucle > 100 µL pour une colonne de 4.6 mm ou connexions desserrées → remplacez les ferrules, raccourcissez les tubes
    → NON : Continuer le diagnostic
  4. 4. Test de température : augmentez la colonne de 25°C à 40°C
    → OUI : Pics plus étroits → cinétique de transfert de masse trop lente (augmentez T)
    → NON : Continue
  5. 5. Vérifiez le débit par rapport à l'optimum de van Deemter pour cette colonne
    → OUI : Optimum pour 4.6mm/5µm = 1.0 mL/min, pour 2.1mm/3µm = 0.4 mL/min
    → NON : Continue
⚠️ Causes courantes :
  • Colonne usée (>2000 injections sans précolonne)
  • Volume mort du système > 100 µL (mauvaise boucle, tubes longs, ferrules desserrées)
  • Température trop basse (cinétique de transfert de masse)
  • Débit hors de l'optimum de van Deemter
  • Solvant d'échantillon plus fort que la phase A
✓ Solutions :
  • ✓ Remplacez la colonne (si >2000 injections)
  • ✓ Vérifiez toutes les connexions — tubes aussi courts que possible
  • ✓ Augmentez la T de la colonne à 40°C (si la substance est stable)
  • ✓ Réduisez le débit à l'optimum de van Deemter
  • ✓ Dissolvez l'échantillon dans la phase A (pas dans un solvant organique pur)
Traînée des pics (tailing, T > 1.5) high

Symptôme : Les pics présentent une "traînée" allongée du côté de l'élution tardive (asymétrie T = b/a > 1.5 selon l'USP)

🔍 Arbre diagnostique :
  1. 1. La substance contient-elle des groupes basiques (amino, pyridine) ?
    → OUI : Oui → interactions silanol ! Ajoutez 0.1% de TFA ou 5-10 mM de TEA à la phase A.
    → NON : Continue
  2. 2. Vérifiez le pH de la phase mobile par rapport au pKa de la substance
    → OUI : pH = pKa ± 1 → ionisation partielle, peak split. Placez le pH à ≥ 2 unités du pKa.
    → NON : Continue
  3. 3. Vérifiez l'âge de la colonne (>1500 injections ?)
    → OUI : Oui → silanols exposés (column bleed). Remplacez par une colonne à endcapping supérieur (XTerra, Symmetry).
    → NON : Continue
  4. 4. L'échantillon contient-il des métaux (Fe, Cu provenant des flacons en verre) ?
    → OUI : Oui → utilisez des flacons incolores de type II ou en PFA. EDTA 0.1mM dans l'échantillon.
    → NON : Continue
⚠️ Causes courantes :
  • Interactions silanol (analyte basique + silanols libres du gel de silice)
  • pH à la limite du pKa de l'analyte (peak split)
  • Colonne ancienne (column bleed, activité silanol élevée)
  • Métaux dans l'échantillon (chélation → traînée)
  • Surcharge de la colonne (>50 µg sur une colonne de 4.6mm)
✓ Solutions :
  • ✓ Ajoutez 0.1% de TFA (UV) ou 0.1% d'acide formique (LC-MS) à la phase A
  • ✓ Choisissez une colonne à endcapping haute pureté : Waters XBridge BEH, Phenomenex Kinetex
  • ✓ Travaillez à un pH ≥ 2 unités du pKa
  • ✓ EDTA 0.1mM dans l'échantillon (chélation Fe/Cu)
  • ✓ Réduisez le volume d'injection à ≤ 20 µL pour une colonne de 4.6mm
Dérive de la ligne de base (baseline drift) medium

Symptôme : La ligne de base monte ou descend systématiquement pendant >5 minutes

🔍 Arbre diagnostique :
  1. 1. Utilisez-vous un gradient (B% augmente) ?
    → OUI : Oui → absorption différente des phases A vs B à dλ. Changement de solvant dans la coupure UV. Vérifiez l'absorbance UV du % d'organique.
    → NON : Continuer (isocratique)
  2. 2. Vérifiez la température de la colonne — est-elle stable à ±0.5°C ?
    → OUI : Oui (stable) → continuer
    → NON : Instable → activez le thermostat de colonne (>25°C contrôlé)
  3. 3. Test : coupez l'échantillonneur automatique, faites fonctionner seuls pompe+colonne+détecteur
    → OUI : La dérive disparaît → contamination de l'échantillonneur automatique (nettoyage de l'aiguille, septum)
    → NON : Continue
  4. 4. Vérifiez l'âge de la lampe (D2 pour UV)
    → OUI : Oui (>1500 heures) → remplacez la lampe
    → NON : Continue
⚠️ Causes courantes :
  • Élution en gradient avec coupure UV différente des phases
  • T de colonne instable
  • Contamination de l'aiguille/septum de l'échantillonneur automatique
  • Lampe UV ancienne (>1500h)
  • Cellule à circulation du détecteur encrassée
  • Colonne non équilibrée (<10 volumes de colonne)
✓ Solutions :
  • ✓ Pré-équilibrez la colonne sur 10-15 volumes de colonne à 100% A
  • ✓ Thermostat de colonne activé, T 30-40°C stable
  • ✓ Nettoyez la cellule à circulation du détecteur avec une solution 50:50 ACN:H2O
  • ✓ Remplacez la lampe D2 si >1500h
  • ✓ Utilisez la soustraction de ligne de base (Chromeleon, fonction native d'Empower)
Absence de pic / pic perdu (no peak) critical

Symptôme : Le pic d'analyte attendu n'apparaît pas sur le chromatogramme

🔍 Arbre diagnostique :
  1. 1. L'injection a-t-elle réellement eu lieu ?
    → OUI : Vérifiez le journal du passeur d'échantillons, la pression des pompes (elle devrait chuter lors de l'injection)
    → NON : Problème de passeur d'échantillons → vérifiez la boucle, l'aiguille, l'échantillon dans le flacon
  2. 2. L'échantillon est-il dans le flacon (volume correct, non évaporé) ?
    → OUI : Continue
    → NON : Pas d'échantillon — repipetez
  3. 3. Stabilité de l'échantillon — préparé il y a >24h ?
    → OUI : Oui → dégradation. Préparez un nouvel échantillon frais.
    → NON : Continue
  4. 4. Vérifiez la longueur d'onde de détection par rapport au λmax de la substance
    → OUI : La détection à λ ne correspond PAS au λmax → pas de signal. Scannez le DAD 200-400nm.
    → NON : Continue
  5. 5. Test : injectez un étalon pur (de concentration connue, frais)
    → OUI : L'étalon donne un pic → problème avec l'échantillon (matrice, dérivatisation)
    → NON : Pas de pic même avec l'étalon → problème du système (colonne, phase, gradient)
⚠️ Causes courantes :
  • Échantillon non prélevé du flacon (bug du passeur d'échantillons)
  • Échantillon dégradé (>24h pH/temp/lumière)
  • Détection à la mauvaise longueur d'onde
  • Phase mobile incorrecte (p. ex. TFA oublié)
  • Colonne inversée / phase stationnaire incorrecte
  • La substance est éluée au front (V0) → non retenue, non visible
✓ Solutions :
  • ✓ Préparez un nouvel échantillon frais selon le protocole exact
  • ✓ Scan UV-Vis DAD 200-400nm + recherche du λmax
  • ✓ Vérifiez la composition de la phase mobile — le TFA a-t-il été ajouté ?
  • ✓ Testez le sens inverse de la colonne (prudemment !)
  • ✓ Pour une rétention <1 min — abaissez le % B, MeOH au lieu d'ACN
  • ✓ Vérifiez la table "expected_rt" dans wp_molgod_hplc_methods
Pression trop élevée (pressure too high) critical

Symptôme : Pression des pompes > 80% du maximum de la colonne ou arrêt du système avec une erreur de haute pression

🔍 Arbre diagnostique :
  1. 1. Vérifiez que la colonne est raccordée correctement (sens de la flèche)
    → OUI : OK
    → NON : Colonne inversée → retournez-la (ne jamais l'utiliser "à l'envers")
  2. 2. Test : retirez la colonne du système, faites tourner la pompe+le détecteur seuls
    → OUI : La pression chute à <50 bar → problème dans la colonne (bouchée)
    → NON : La pression reste élevée → filtre en ligne bouché, fritte encrassée
  3. 3. Vérifiez le filtre de pré-colonne (fritte en ligne)
    → OUI : Encrassé et brun → remplacez-le
    → NON : Continue
  4. 4. Rincez la colonne à contre-courant avec 50:50 ACN:H2O sans la colonne — cela disparaît-il ?
    → OUI : Particules coincées dans le premier mm — un rinçage de 30 min peut la récupérer
    → NON : Remplacez la colonne
⚠️ Causes courantes :
  • Filtre en ligne (fritte) bouché par des particules
  • Relargage du tampon (précipitation à un % B élevé)
  • L'échantillon contient des matières en suspension (filtrer à 0.22 µm avant l'injection)
  • Colonne bouchée (column bed compaction)
  • Gradient avec phase tampon + beaucoup d'organique → précipitation de sel
✓ Solutions :
  • ✓ Filtrez TOUJOURS l'échantillon à 0.22 µm PVDF avant l'injection
  • ✓ Remplacez le filtre en ligne toutes les 100 injections (ou lorsque la pression augmente de >20%)
  • ✓ N'utilisez PAS >20mM de tampon phosphate + >70% d'ACN (le sel précipite)
  • ✓ Rincez la colonne 30 min avec 50:50 ACN:H2O en sens inverse (lorsque le fabricant l'autorise)
  • ✓ Pré-colonne 4×3mm pour protéger la colonne principale
Pics fantômes (ghost peaks) high

Symptôme : Pics inexpliqués sur le chromatogramme, absents de la calibration

🔍 Arbre diagnostique :
  1. 1. Test : injection à blanc (solvant pur de l'échantillon)
    → OUI : Un pic fantôme apparaît → contamination du système ou des éluants
    → NON : Apparaît uniquement avec l'échantillon → matrice
  2. 2. Le pic fantôme croît-il avec le gradient (élue à % B élevé) ?
    → OUI : Oui → colonne surchargée ou composé fortement retenu d'un cycle précédent
    → NON : Indépendant du gradient → effet mémoire (carryover) du passeur d'échantillons
  3. 3. Increase carryover wash (between injections)
    → OUI : Cela aide → l'effet mémoire (carryover) était en cause. Protocole de lavage plus puissant.
    → NON : Continue
  4. 4. Injection d'eau pure — y a-t-il un pic ?
    → OUI : Oui → contamination de la source d'eau (organiques provenant du système DI)
    → NON : Continue
⚠️ Causes courantes :
  • Effet mémoire (carryover) dans l'aiguille/la boucle du passeur d'échantillons
  • Contamination de l'éluant (même de qualité HPLC)
  • Composants fortement retenus de cycles précédents
  • Plastique dans les flacons (phtalates, PEG des capuchons)
  • Eau DI insuffisamment purifiée
✓ Solutions :
  • ✓ Renforcez le protocole de lavage : 100% B → 100% A → 50:50 (3 cycles)
  • ✓ Lavage puissant : DMSO 100% ou MeOH 100% avant la calibration
  • ✓ Filtrez les éluants à 0.22 µm PTFE en cas de doute
  • ✓ Utilisez du verre ambré + des capuchons à revêtement Téflon pour les échantillons
  • ✓ Rampe de gradient périodique jusqu'à 100% B pendant 10 min (nettoyage)

📚 FAQ technique — Aceton (5) MolGod_TECHFAQ_1
❓ Jak przygotować roztwór standardowy acetonu o stężeniu 1 mol/L?
Aby przygotować roztwór standardowy acetonu (CAS 67-64-1) o stężeniu 1 mol/L, należy odważyć masę substancji zgodnie ze wzorem: masa [g] = stężenie [mol/L] × objętość [L] × masa molowa [g/mol]. Dla 1 mol/L i 1 L roztworu, masa acetonu wynosi: 1 mol/L × 1 L × 58.08 g/mol = 58.08 g. Następnie rozpuścić 58.08 g acetonu w wodzie destylowanej do objętości 1 L.
Utile ?
❓ W jakich warunkach należy przechowywać aceton czysty (CAS 67-64-1)?
Aceton czysty (CAS 67-64-1) powinien być przechowywany w temperaturze pokojowej (15-25°C), z dala od bezpośredniego światła słonecznego i źródeł ciepła. Wilgotność względna powietrza nie powinna przekraczać 60%. Przechowywać w szczelnie zamkniętym pojemniku, aby uniknąć parowania i zanieczyszczenia.
Utile ?
❓ Jaka metoda analityczna jest odpowiednia do analizy acetonu (CAS 67-64-1) w zależności od jego logP?
Dla acetonu (logP ≈ -0.9), ze względu na niską lipofilność i masę molową 58.08 g/mol, zalecaną metodą analityczną jest chromatografia gazowa (GC) z detektorem płomieniowo-jonizacyjnym (FID). Alternatywnie, można zastosować wysokosprawną chromatografię cieczową (HPLC) z odpowiednim układem fazowym, jeśli wymagana jest wyższa rozdzielczość lub analiza w środowisku wodnym.
Utile ?
❓ Jakie są potencjalne reaktywności i niezgodności chemiczne acetonu (CAS 67-64-1)?
Aceton (CAS 67-64-1) jest rozpuszczalnikiem polarnym, ale może reagować z silnymi utleniaczami (np. nadtlenkami) oraz kwasami nieorganicznymi w wysokich temperaturach. Nie należy go mieszać z reduktorami organicznymi (np. NaBH4), które mogą prowadzić do egzotermicznych reakcji. Aceton jest również niekompatybilny z niektórymi tworzywami sztucznymi, takimi jak polistyren i polietylen, które może rozpuszczać.
Utile ?
❓ W jakich praktycznych zastosowaniach laboratoryjnych wykorzystuje się aceton (CAS 67-64-1)?
Aceton (CAS 67-64-1) jest powszechnie stosowany jako rozpuszczalnik w syntezie organicznej, np. do rozpuszczania tłuszczów, olejów i żywic. Służy również do oczyszczania szkła laboratoryjnego, jako eluent w chromatografii oraz jako środek do usuwania lakierów i powłok. W analizie chemicznej wykorzystuje się go do przygotowania próbek i rozcieńczania ekstraktów.
