🔧 HPLC troubleshooting — decision tree 6 common problems

Diagnostics for the 6 most common HPLC problems with a decision tree (5 steps per problem). Source: Snyder/Kirkland/Dolan 3rd ed. Chapter 17 + LCGC LC Troubleshooting columns 1989-2024.

Broad peaks medium

Symptom: All peaks on the chromatogram are wider than expected (FWHM > 2× normal)

🔍 Diagnostic tree:
  1. 1. Check whether all peaks are broadened or only some
    → YES: All → instrumental problem (column or system)
    → NO: Only some → chemistry problem (interaction with the column for specific analytes)
  2. 2. Swap in a test column — does the problem disappear?
    → YES: COLUMN worn out — packing damaged, void in the first few mm. Replace it.
    → NO: Problem in the LC system
  3. 3. Check the dead volume — injection loop, connections, detector
    → YES: Loop > 100 µL for a 4.6 mm column or loose connections → replace ferrules, shorten tubing
    → NO: Continue diagnostics
  4. 4. Temperature test: raise the column from 25°C to 40°C
    → YES: Narrower peaks → mass-transfer kinetics too slow (increase T)
    → NO: Continue
  5. 5. Check flow rate vs the optimal van Deemter value for this column
    → YES: Optimum for 4.6mm/5µm = 1.0 mL/min, for 2.1mm/3µm = 0.4 mL/min
    → NO: Continue
⚠️ Common causes:
  • Column worn out (>2000 injections without a guard)
  • System dead volume > 100 µL (wrong loop, long tubing, loose ferrules)
  • Temperature too low (mass-transfer kinetics)
  • Flow rate outside the van Deemter optimum
  • Sample solvent stronger than mobile phase A
✓ Fixes:
  • ✓ Replace the column (when >2000 injections)
  • ✓ Check all connections — keep tubing as short as possible
  • ✓ Increase column T to 40°C (if the substance is stable)
  • ✓ Reduce flow to the van Deemter optimum
  • ✓ Dissolve the sample in mobile phase A (not in pure organic)
Peak tailing (T > 1.5) high

Symptom: Peaks have an extended "tail" on the late-elution side (asymmetry T = b/a > 1.5 per USP)

🔍 Diagnostic tree:
  1. 1. Does the substance contain basic groups (amino, pyridine)?
    → YES: Yes → silanol interactions! Add 0.1% TFA or 5-10 mM TEA to mobile phase A.
    → NO: Continue
  2. 2. Check the mobile-phase pH vs the substance pKa
    → YES: pH = pKa ± 1 → partial ionization, peak split. Move pH ≥ 2 units away from pKa.
    → NO: Continue
  3. 3. Check the column age (>1500 injections?)
    → YES: Yes → exposed silanols (column bleed). Replace with a column with higher endcapping (XTerra, Symmetry).
    → NO: Continue
  4. 4. Does the sample contain metals (Fe, Cu from glass vials)?
    → YES: Yes → use type II clear vials or PFA. Add 0.1mM EDTA to the sample.
    → NO: Continue
⚠️ Common causes:
  • Silanol interactions (basic analyte + silica gel free silanols)
  • pH at the boundary of the analyte pKa (peak split)
  • Old column (column bleed, high silanol activity)
  • Metals in the sample (chelation → tailing)
  • Column overload (>50 µg on a 4.6mm column)
✓ Fixes:
  • ✓ Add 0.1% TFA (UV) or 0.1% formic acid (LC-MS) to mobile phase A
  • ✓ Choose a column with high-purity endcapping: Waters XBridge BEH, Phenomenex Kinetex
  • ✓ Work at pH ≥ 2 units away from pKa
  • ✓ Add 0.1mM EDTA to the sample (Fe/Cu chelation)
  • ✓ Reduce the injection volume to ≤ 20 µL for a 4.6mm column
Baseline drift medium

Symptom: The baseline rises or falls systematically for >5 minutes

🔍 Diagnostic tree:
  1. 1. Are you running a gradient (B% increasing)?
    → YES: Yes → different absorption of phases A vs B at dλ. Solvent change in UV cutoff. Check the % organic UV absorbance.
    → NO: Continue (isocratic)
  2. 2. Check the column temperature — is it stable to ±0.5°C?
    → YES: Yes (stable) → continue
    → NO: Unstable → turn on the column thermostat (>25°C controlled)
  3. 3. Test: turn off the autosampler, run pump+column+detector alone
    → YES: Drift disappears → autosampler contamination (clean the needle, septum)
    → NO: Continue
  4. 4. Check the lamp age (D2 for UV)
    → YES: Yes (>1500 hours) → replace the lamp
    → NO: Continue
⚠️ Common causes:
  • Gradient elution with different UV cutoff of the phases
  • Unstable column T
  • Autosampler contamination of the needle/septum
  • Old UV lamp (>1500h)
  • Detector flow cell fouled
  • Column not equilibrated (<10 column volumes)
✓ Fixes:
  • ✓ Pre-equilibrate the column for 10-15 column volumes at 100% A
  • ✓ Column thermostat on, T 30-40°C stable
  • ✓ Clean the detector flow cell with 50:50 ACN:H2O
  • ✓ Replace the D2 lamp if >1500h
  • ✓ Use baseline subtraction (Chromeleon, Empower native function)
No peak / lost peak critical

Symptom: The expected analyte peak does not appear on the chromatogram

🔍 Diagnostic tree:
  1. 1. Did the injection actually take place?
    → YES: Check the autosampler log, pump pressure (should drop during injection)
    → NO: Autosampler problem → check the loop, needle, sample in the vial
  2. 2. Is the sample in the vial (correct volume, not evaporated)?
    → YES: Continue
    → NO: No sample — re-pipette
  3. 3. Sample stability — prepared >24h ago?
    → YES: Yes → degradation. Re-prepare a fresh sample.
    → NO: Continue
  4. 4. Check the detection wavelength vs the substance λmax
    → YES: Detection at λ does NOT match λmax → no signal. Scan DAD 200-400nm.
    → NO: Continue
  5. 5. Test: inject a pure standard (of known concentration, fresh)
    → YES: The standard gives a peak → problem with the sample (matrix, derivatization)
    → NO: No peak even with the standard → system problem (column, phase, gradient)
⚠️ Common causes:
  • Sample not drawn from the vial (autosampler bug)
  • Sample degraded (>24h pH/temp/light)
  • Detection at the wrong wavelength
  • Wrong mobile phase (e.g. forgotten TFA)
  • Column reversed / wrong stationary phase
  • Substance elutes at the front (V0) → unretained, not visible
✓ Fixes:
  • ✓ Re-prepare a fresh sample per the exact protocol
  • ✓ UV-Vis DAD scan 200-400nm + search for λmax
  • ✓ Check the mobile-phase composition — was TFA added?
  • ✓ Test the reverse column direction (carefully!)
  • ✓ For retention <1 min — lower the % B, MeOH instead of ACN
  • ✓ Check the expected retention time in the plugin method database
Pressure too high critical

Symptom: Pump pressure > 80% of the column max or system shutdown with a high-pressure error

🔍 Diagnostic tree:
  1. 1. Check that the column is connected correctly (arrow direction)
    → YES: OK
    → NO: Column reversed → flip it (never run it "backwards")
  2. 2. Test: remove the column from the system, run pump+detector alone
    → YES: Pressure drops to <50 bar → problem in the column (clogged)
    → NO: Pressure stays high → in-line filter clogged, frit fouled
  3. 3. Check the pre-column filter (in-line frit)
    → YES: Fouled and brown → replace it
    → NO: Continue
  4. 4. Back-flush the column with 50:50 ACN:H2O without the column — does it disappear?
    → YES: Particles stuck in the first mm — a 30 min flush may recover it
    → NO: Replace the column
⚠️ Common causes:
  • In-line filter (frit) clogged with particles
  • Buffer salting out (precipitation at high %B)
  • Sample contains suspended matter (filter 0.22 µm before injection)
  • Column clogged (column bed compaction)
  • Gradient with a buffer phase + high organic → salt precipitation
✓ Fixes:
  • ✓ ALWAYS filter the sample through 0.22 µm PVDF before injection
  • ✓ Replace the in-line filter every 100 injections (or when pressure rises >20%)
  • ✓ Do NOT use >20mM phosphate buffer + >70% ACN (the salt precipitates)
  • ✓ Flush the column for 30 min with 50:50 ACN:H2O in the reverse direction (when the manufacturer allows it)
  • ✓ Pre-column 4×3mm to protect the main column
Ghost peaks high

Symptom: Unexplained peaks on the chromatogram absent from the calibration

🔍 Diagnostic tree:
  1. 1. Test: blank injection (pure sample solvent)
    → YES: A ghost appears → contamination of the system or eluents
    → NO: Appears only with the sample → matrix
  2. 2. Does the ghost grow with the gradient (elutes at high %B)?
    → YES: Yes → overloaded column or strong-retained from a previous run
    → NO: Independent of the gradient → autosampler carryover
  3. 3. Increase carryover wash (between injections)
    → YES: Helps → carryover was to blame. Use a stronger wash protocol.
    → NO: Continue
  4. 4. Pure water injection — is there a peak?
    → YES: Yes → contamination of the water source (organics from the DI system)
    → NO: Continue
⚠️ Common causes:
  • Carryover in the autosampler needle/loop
  • Eluent contamination (even HPLC-grade)
  • Strong-retained components from previous runs
  • Plastic in the vials (phthalates, PEG from the caps)
  • Insufficiently purified DI water
✓ Fixes:
  • ✓ Strengthen the wash protocol: 100% B → 100% A → 50:50 (3 cycles)
  • ✓ Strong wash: 100% DMSO or 100% MeOH before calibration
  • ✓ Filter the eluents through 0.22 µm PTFE if in doubt
  • ✓ Use amber glass + Teflon-lined caps for samples
  • ✓ Periodic gradient ramp to 100% B for 10 min (clean-out)

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

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.
