Qiu Y, Ma C. HPLC, quantitative NMR and HRMS spectroscopic data of nusbiarylins as a new class of antimicrobial agents. Data in Brief. 2020;29:105313. doi:10.1016/j.dib.2020.105313
Bacterial transcription is a valid but underutilized target for antimicrobial agent discovery [1]. Nusbiarylins are the first-in-class bacterial ribosomal RNA synthesis inhibitors that possess potent activity against various types of multidrug-resistant bacteria with a novel mode of action by targeting the interaction of bacterial transcription factors NusB and NusE [2]. To facilitate the characterization of nusbiarylin derivatives produced by other researchers, high-performance liquid chromatography (HPLC) profiles, quantitative nuclear magnetic resonance (qNMR) and high-resolution mass spectrometry (HRMS) spectroscopic data were presented for the quick determination of purity and characterization of 95 nusbiarylin compounds. The data presented in this article supplement the 1H and 13C NMR data provided previously [3,4], and assist the reproduction of nusbiarylins for chemical, biological and drug discovery research.

🔧 HPLC-troubleshooting — beslissingsboom 6 veelvoorkomende problemen

Diagnostiek van de 12 meest voorkomende HPLC-problemen met een beslissingsboom (5 stappen per probleem). Bron: Snyder/Kirkland/Dolan 3rd ed. Chapter 17 + LCGC LC Troubleshooting columns 1989-2024.

Verbrede pieken (broad peaks) medium

Symptoom: Alle pieken op het chromatogram zijn breder dan verwacht (FWHM > 2× normaal)

🔍 Diagnostische boom:
  1. 1. Controleer of alle pieken verbreed zijn of slechts sommige
    → JA: Alle → instrumenteel probleem (kolom of systeem)
    → NEE: Slechts sommige → chemisch probleem (interactie met de kolom voor specifieke analyten)
  2. 2. Verwissel met een testkolom — verdwijnt het probleem?
    → JA: KOLOM versleten — packing beschadigd, void in de eerste mm. Vervang hem.
    → NEE: Probleem in het LC-systeem
  3. 3. Controleer het dode volume (dead volume) — injectielus, verbindingen, detector
    → JA: Lus > 100 µL voor een 4.6 mm kolom of losse verbindingen → vervang de ferrules, kort de leidingen in
    → NEE: Diagnostiek voortzetten
  4. 4. Temperatuurtest: verhoog de kolom van 25°C naar 40°C
    → JA: Smallere pieken → massatransferkinetiek te traag (verhoog T)
    → NEE: Continue
  5. 5. Controleer het debiet t.o.v. het van Deemter-optimum voor deze kolom
    → JA: Optimum voor 4.6mm/5µm = 1.0 mL/min, voor 2.1mm/3µm = 0.4 mL/min
    → NEE: Continue
⚠️ Typische oorzaken:
  • Kolom versleten (>2000 injecties zonder voorkolom)
  • Dood volume van het systeem > 100 µL (verkeerde lus, lange leidingen, losse ferrules)
  • Temperatuur te laag (massatransferkinetiek)
  • Debiet buiten het van Deemter-optimum
  • Monsteroplosmiddel sterker dan mobiele fase A
✓ Oplossingen:
  • ✓ Vervang de kolom (bij >2000 injecties)
  • ✓ Controleer alle verbindingen — houd de leidingen zo kort mogelijk
  • ✓ Verhoog de kolomtemperatuur naar 40°C (als de stof stabiel is)
  • ✓ Verlaag het debiet naar het van Deemter-optimum
  • ✓ Los het monster op in mobiele fase A (niet in puur organisch)
Piektailing (tailing, T > 1.5) high

Symptoom: Pieken hebben een verlengde "staart" aan de late-elutiezijde (asymmetrie T = b/a > 1.5 volgens USP)

🔍 Diagnostische boom:
  1. 1. Bevat de stof basische groepen (amino, pyridine)?
    → JA: Ja → silanolinteracties! Voeg 0.1% TFA of 5-10 mM TEA toe aan mobiele fase A.
    → NEE: Continue
  2. 2. Controleer de pH van de mobiele fase t.o.v. de pKa van de stof
    → JA: pH = pKa ± 1 → gedeeltelijke ionisatie, peak split. Verplaats de pH ≥ 2 eenheden weg van de pKa.
    → NEE: Continue
  3. 3. Controleer de leeftijd van de kolom (>1500 injecties?)
    → JA: Ja → blootgelegde silanolen (column bleed). Vervang door een kolom met hogere endcapping (XTerra, Symmetry).
    → NEE: Continue
  4. 4. Bevat het monster metalen (Fe, Cu uit glazen flesjes)?
    → JA: Ja → gebruik kleurloze type II-flesjes of PFA. Voeg 0.1mM EDTA toe aan het monster.
    → NEE: Continue
⚠️ Typische oorzaken:
  • Silanolinteracties (basische analyt + vrije silanolen van silicagel)
  • pH op de grens van de pKa van de analyt (peak split)
  • Oude kolom (column bleed, hoge silanolactiviteit)
  • Metalen in het monster (chelatie → tailing)
  • Kolomoverbelasting (>50 µg op een 4.6mm kolom)
✓ Oplossingen:
  • ✓ Voeg 0.1% TFA (UV) of 0.1% mierenzuur (LC-MS) toe aan mobiele fase A
  • ✓ Kies een kolom met hoogzuivere endcapping: Waters XBridge BEH, Phenomenex Kinetex
  • ✓ Werk bij een pH ≥ 2 eenheden weg van de pKa
  • ✓ 0.1mM EDTA aan het monster (Fe/Cu-chelatie)
  • ✓ Verlaag het injectievolume naar ≤ 20 µL voor een 4.6mm kolom
Basislijndrift (baseline drift) medium

Symptoom: De basislijn stijgt of daalt systematisch gedurende >5 minuten

🔍 Diagnostische boom:
  1. 1. Gebruik je een gradiënt (B% neemt toe)?
    → JA: Ja → verschillende absorptie van fasen A vs B bij dλ. Oplosmiddelwisseling in de UV-cutoff. Controleer de UV-absorptie van het % organisch.
    → NEE: Verder (isocratisch)
  2. 2. Controleer de kolomtemperatuur — is deze stabiel tot ±0.5°C?
    → JA: Ja (stabiel) → verder
    → NEE: Instabiel → schakel de kolomthermostaat in (>25°C gecontroleerd)
  3. 3. Test: schakel de autosampler uit, laat alleen pomp+kolom+detector draaien
    → JA: De drift verdwijnt → contaminatie van de autosampler (reinig de naald, het septum)
    → NEE: Continue
  4. 4. Controleer de leeftijd van de lamp (D2 voor UV)
    → JA: Ja (>1500 uur) → vervang de lamp
    → NEE: Continue
⚠️ Typische oorzaken:
  • Gradiëntelutie met verschillende UV-cutoff van de fasen
  • Instabiele kolomtemperatuur
  • Autosampler-contaminatie van de naald/septum
  • UV-lamp oud (>1500h)
  • Detector-flowcel vervuild
  • Kolom niet geëquilibreerd (<10 kolomvolumes)
✓ Oplossingen:
  • ✓ Kolom voor-equilibreren gedurende 10-15 kolomvolumes bij 100% A
  • ✓ Kolomthermostaat aan, T 30-40°C stabiel
  • ✓ Reinig de detector-flowcel met een 50:50 ACN:H2O-oplossing
  • ✓ Vervang de D2-lamp indien >1500h
  • ✓ Gebruik baseline subtraction (Chromeleon, native Empower-functie)
Geen piek / verloren piek (no peak) critical

Symptoom: De verwachte analytpiek verschijnt niet op het chromatogram

🔍 Diagnostische boom:
  1. 1. Heeft de injectie daadwerkelijk plaatsgevonden?
    → JA: Controleer het autosampler-log, de pompdruk (moet dalen tijdens de injectie)
    → NEE: Autosampler-probleem → controleer de loop, de naald, het monster in de vial
  2. 2. Zit het monster in de vial (correct volume, niet verdampt)?
    → JA: Continue
    → NEE: Geen monster — opnieuw pipetteren
  3. 3. Monsterstabiliteit — >24h geleden bereid?
    → JA: Ja → degradatie. Bereid een vers monster opnieuw.
    → NEE: Continue
  4. 4. Controleer de detectiegolflengte t.o.v. de λmax van de stof
    → JA: Detectie bij λ komt NIET overeen met λmax → geen signaal. Scan DAD 200-400nm.
    → NEE: Continue
  5. 5. Test: injecteer een zuivere standaard (van bekende concentratie, vers)
    → JA: De standaard geeft een piek → probleem met het monster (matrix, derivatisering)
    → NEE: Ook geen piek met de standaard → systeemprobleem (kolom, fase, gradiënt)
⚠️ Typische oorzaken:
  • Monster niet uit de vial genomen (autosampler-bug)
  • Monster gedegradeerd (>24h pH/temp/licht)
  • Detectie bij de verkeerde golflengte
  • Verkeerde mobiele fase (bijv. vergeten TFA)
  • Kolom omgekeerd / verkeerde stationaire fase
  • De stof elueert op het front (V0) → niet vastgehouden, niet zichtbaar
✓ Oplossingen:
  • ✓ Bereid een vers monster opnieuw volgens het exacte protocol
  • ✓ UV-Vis DAD-scan 200-400nm + zoeken naar λmax
  • ✓ Controleer de samenstelling van de mobiele fase — is TFA toegevoegd?
  • ✓ Test de omgekeerde kolomrichting (voorzichtig!)
  • ✓ Voor retentie <1 min — verlaag de % B, MeOH in plaats van ACN
  • ✓ Controleer de tabel "expected_rt" in wp_molgod_hplc_methods
Druk te hoog (pressure too high) critical

Symptoom: Pompdruk > 80% van het kolommaximum of systeem-shutdown met high-pressure error

🔍 Diagnostische boom:
  1. 1. Controleer of de kolom correct is aangesloten (richting van de pijl)
    → JA: OK
    → NEE: Kolom omgekeerd → draai om (nooit "achterstevoren" gebruiken)
  2. 2. Test: verwijder de kolom uit het systeem, laat alleen pomp+detector draaien
    → JA: Druk daalt naar <50 bar → probleem in de kolom (verstopt)
    → NEE: Druk blijft hoog → in-line filter verstopt, frit vervuild
  3. 3. Controleer het pre-kolomfilter (in-line frit)
    → JA: Vervuild en bruin → vervangen
    → NEE: Continue
  4. 4. Spoel de kolom terug met 50:50 ACN:H2O zonder de kolom — verdwijnt het?
    → JA: Deeltjes vast in de eerste mm — een flush van 30 min kan het herstellen
    → NEE: Vervang de kolom
⚠️ Typische oorzaken:
  • In-line filter (frit) verstopt met deeltjes
  • Buffer salting-out (precipitatie bij hoog %B)
  • Monster bevat zwevende deeltjes (filtreer 0.22 µm vóór injectie)
  • Kolom verstopt (column bed compaction)
  • Gradiënt met bufferfase + veel organisch → zoutprecipitatie
✓ Oplossingen:
  • ✓ Filtreer het monster ALTIJD door 0.22 µm PVDF vóór injectie
  • ✓ Vervang het in-line filter elke 100 injecties (of wanneer de druk >20% stijgt)
  • ✓ Gebruik GEEN >20mM fosfaatbuffer + >70% ACN (het zout slaat neer)
  • ✓ Spoel de kolom 30 min met 50:50 ACN:H2O in de omgekeerde richting (wanneer de fabrikant dit toestaat)
  • ✓ Pre-kolom 4×3mm ter bescherming van de hoofdkolom
Spookpieken (ghost peaks) high

Symptoom: Onverklaarde pieken op het chromatogram die afwezig zijn in de kalibratie

🔍 Diagnostische boom:
  1. 1. Test: blanco injectie (zuiver monsteroplosmiddel)
    → JA: Er verschijnt een spookpiek → contaminatie van het systeem of de eluenten
    → NEE: Verschijnt alleen bij het monster → matrix
  2. 2. Groeit de spookpiek met de gradiënt (elueert bij hoog %B)?
    → JA: Ja → overladen kolom of sterk vastgehouden uit een vorige run
    → NEE: Onafhankelijk van de gradiënt → autosampler carryover
  3. 3. Increase carryover wash (between injections)
    → JA: Helpt → carryover was de oorzaak. Sterker wasprotocol.
    → NEE: Continue
  4. 4. Injectie van zuiver water — is er een piek?
    → JA: Ja → contaminatie van de waterbron (organische stoffen uit het DI-systeem)
    → NEE: Continue
⚠️ Typische oorzaken:
  • Carryover in de autosampler-naald/loop
  • Contaminatie van het eluens (zelfs HPLC-grade)
  • Sterk vastgehouden componenten uit vorige runs
  • Plastic in de vials (ftalaten, PEG uit de doppen)
  • DI-water onvoldoende gezuiverd
✓ Oplossingen:
  • ✓ Versterk het wasprotocol: 100% B → 100% A → 50:50 (3 cycli)
  • ✓ Sterke was: 100% DMSO of 100% MeOH vóór de kalibratie
  • ✓ Filtreer de eluenten door 0.22 µm PTFE bij twijfel
  • ✓ Gebruik amberkleurig glas + doppen met Teflon-coating voor monsters

Description

GLUKOZA DEKSTROZA – 1KG

  • Postać: biały drobnokrystliczny proszek
  • Składniki: 100% Glukozy
  • Przedmiotem wymagań jest glukoza krystaliczna przeznaczona do celów spożywczych. Glukoza krystaliczna (α-D-glukoza) w postaci drobnokrystalicznej jest otrzymywana w wyniku enzymatycznej hydrolizy skrobii.
  • Opakowanie typu “doypack” pozwala na zachowanie długiej świeżości, gdyż można takie opakowanie wielokrotnie otwierać i zamykać
  • Masa netto: 1000 g

Termin ważności i kraj pochodzenia na opakowaniu produktu lub zapytaj sprzedającego poprzez formularz .

Glukoza, zwana także cukrem krwi, jest jednym z najważniejszych cukrów prostych, które stanowią źródło energii dla organizmu. Jest to monosacharyd o wzorze sumarycznym C6H12O6, który wytwarzany jest w procesie fotosyntezy przez rośliny oraz niektóre mikroorganizmy.

W organizmie ludzkim glukoza jest metabolizowana w procesie glikolizy, czyli przemiany chemicznej, która pozwala na uzyskanie energii. Glukoza jest transportowana przez krew do tkanek i komórek, gdzie jest wykorzystywana do produkcji energii, wytwarzania glikogenu, który stanowi zapas energii w organizmie, lub do syntezy innych związków, takich jak kwas mlekowy.

Poziom glukozy we krwi regulowany jest przez hormony takie jak insulinę i glukagon, które są wydzielane przez trzustkę. W przypadku nadmiernego spożycia węglowodanów, organizm magazynuje nadmiar glukozy w postaci glikogenu, który jest magazynowany w wątrobie i mięśniach.

Zastosowanie:

  • przyspiesza fermentację, korzystnie wpływa na bukiet aromatyczny i smak finalnego alkoholu
  • stosowana jest jako środek regulujący słodycz napojów wytwarzanych z udziałem koncentratów soków oraz w produkcji napojów sproszkowanych i gazowanych
  • W przemyśle mięsnym jest składnikiem zalew do szynek.

Przechowywanie: w suchym i ciemnym miejscu w temperaturze pokojowej, w miejscu niedostępnym .

Gwarantujemy, że produkt jest najwyższej jakości !

Glukoza jest powszechnie wykorzystywana w przemyśle spożywczym jako słodzik, zagęszczacz i konserwant. Poniżej przedstawiam kilka przykładów przepisów wykorzystujących glukozę:

Przepis na karmel z glukozą:

  • 200 g cukru
  • 50 g glukozy
  • 100 ml śmietanki 30%
  • szczypta soli

W rondlu o grubym dnie rozgrzej cukier i glukozę, aż się rozpuszczą i zaczną się karmelizować. W międzyczasie podgrzej śmietankę z solą, aż zacznie się gotować. Karmel z cukru i glukozy stopniowo dodawaj do gorącej śmietanki, mieszając cały czas, aż wszystko się połączy. Gotuj na małym ogniu, mieszając przez około 5 minut. Przelej do słoika i pozostaw do wystygnięcia.

Przepis na lizaki z glukozą:

  • 1 szklanka cukru
  • 1/2 szklanki wody
  • 1/4 szklanki glukozy
  • barwniki i aromaty (opcjonalnie)

W rondlu połącz cukier, wodę i glukozę. Podgrzej, mieszając, aż cukier się rozpuści. Gotuj bez mieszania, aż temperatura osiągnie około 150°C. Odstaw z ognia i dodaj barwnik i aromat, mieszając szybko. Wylej na papier do pieczenia, a następnie wsadź patyczek do lizaka. Pozostaw do stężenia i schłodzenia.

Przepis na syrop z glukozą:

  • 1 szklanka cukru
  • 1/2 szklanki wody
  • 1/2 szklanki glukozy

W rondlu połącz cukier, wodę i glukozę. Podgrzewaj mieszając, aż cukier się rozpuści i składniki się połączą. Gotuj na małym ogniu, aż syrop zgęstnieje i osiągnie pożądaną konsystencję. Odstaw z ognia i pozostaw do wystygnięcia. Możesz użyć tego syropu jako dodatek do wypieków, deserów lub napojów.

Nasze produkty pakowane są w solidne, nieprzezroczyste doypacki ze szczelną struną. Takie opakowanie skutecznie chroni zawartość przed wilgocią, światłem i utratą aromatu, a praktyczna struna umożliwia wielokrotne, wygodne zamykanie.
