📈 Analytische Statistik (t-Test · RSD · Grubbs · Q-Dixon) ICH Q2

Fügen Sie eine Serie von Messwiederholungen ein (CSV oder eine Zahl pro Zeile). Der Rechner berechnet Mittelwert, Standardabweichung und 95% CI und erkennt Ausreißer (Grubbs + Dixon Q).

Trennzeichen: Komma, Leerzeichen, Tab, Zeilenumbruch. Min. 3 Messungen.
📐 Statistische Formeln
  • x̄ = Σxᵢ / n — arithmetisches Mittel
  • s² = Σ(xᵢ - x̄)² / (n-1) — Stichprobenvarianz
  • s = √s² — Standardabweichung
  • RSD% = (s / x̄) × 100% — relative Standardabweichung
  • CI₉₅ = x̄ ± t(0.05, n-1) × s / √n — Student's t
  • G = |xᵢ - x̄| / s — Grubbs-Test
  • Q = |xsuspect - xnearest| / |xmax - xmin| — Dixon Q-test

Salhab H, Naughton D, Barker J. Validation of an HPLC Method for the Simultaneous Quantification of Metabolic Reaction Products Catalysed by CYP2C11 Enzymes in Rat Liver Microsomes: In Vitro Inhibitory Effect of Salicylic Acid on CYP2C11 Enzyme. Molecules. 2019;24:4294. doi:10.3390/molecules24234294
The inhibitory effect of new chemical entities on rat liver P450 marker activities was investigated in a functional approach towards drug development. Treatment of colorectal cancer (CRC) and chemoprevention using salicylic acid has gained a lot of attention, mainly in the prevention of the onset of colon cancer. Thus, an in vitro inhibitory effect of salicylic acid on rat CYP2C11 activity was examined by using high performance liquid chromatography (HPLC). High performance liquid chromatography analysis of a CYP2C11 assay was developed on a reversed phase C18 column (SUPELCO 25 cm × 4.6 mm × 5 µm) at 243 nm using 32% phosphate buffer (pH 3.36) and 68% methanol as a mobile phase. The CYP2C11 assay showed good linearity for all components (R2 > 0.999). Substrates and metabolites were found to be stable for up to 72 h. Additionally, the method demonstrated good reproducibility, intra- and inter-day precision (<15%), acceptable recovery and accuracy (80%–120%), and low detection (1.3501 µM and 3.2757 µM) and quantitation limit values (4.914 µM and 9.927 µM) for 16α-hydroxytestosterone and testosterone, respectively. Salicylic acid acts reversibly as a noncompetitive (weak) inhibitor with Ki = 84.582 ± 2.67 µM (concentration of inhibitor to cause 50% inhibition of original enzyme activity (IC50) = 82.70 ± 2.67 µM) for CYP2C11 enzyme activity. This indicates a low potential to cause toxicity and drug–drug interactions.

Salhab H, Naughton D, Barker J. Potential Assessment of UGT2B17 Inhibition by Salicylic Acid in Human Supersomes In Vitro. Molecules. 2021;26:4410. doi:10.3390/molecules26154410
Glucuronidation is a Phase 2 metabolic pathway responsible for the metabolism and excretion of testosterone to a conjugate testosterone glucuronide. Bioavailability and the rate of anabolic steroid testosterone metabolism can be affected upon UGT glucuronidation enzyme alteration. However, there is a lack of information about the in vitro potential assessment of UGT2B17 inhibition by salicylic acid. The purpose of this study is to investigate if UGT2B17 enzyme activity is inhibited by salicylic acid. A UGT2B17 assay was developed and validated by HPLC using a C18 reversed phase column (SUPELCO 25 cm × 4.6 mm, 5 μm) at 246 nm using a gradient elution mobile phase system: (A) phosphate buffer (0.01 M) at pH = 3.8, (B) HPLC grade acetonitrile and (C) HPLC grade methanol. The UGT2B17 metabolite (testosterone glucuronide) was quantified using human UGT2B17 supersomes by a validated HPLC method. The type of inhibition was determined by Lineweaver–Burk plots. These were constructed from the in vitro inhibition of salicylic acid at different concentration levels. The UGT2B17 assay showed good linearity (R2 > 0.99), acceptable recovery and accuracy (80–120%), good reproducibility and acceptable inter and intra-assay precision (<15%), low detection (6.42 and 2.76 μM) and quantitation limit values (19.46 and 8.38 μM) for testosterone and testosterone glucuronide respectively, according to ICH guidelines. Testosterone and testosterone glucuronide were found to be stable up to 72 h in normal laboratory conditions. Our investigational study showed that salicylic acid uncompetitively inhibited UGT2B17 enzyme activity. Thus, drugs that are substrates for the UGT2B17 enzyme have negligible potential effect of causing interaction with salicylic acid in humans.

Back Pressure~150 bar~210 bar (+40%)
UV Cutoff190 nm205 nm
Elution StrengthStrongerWeaker
Price (typical)115 PLN/L70 PLN/L (-39%)
Van Deemter Equation Impact

H = A + B/u + Cu

Higher viscosity (MeOH) → lower optimal flow rate → longer runtime.

Buffer Selection: Why NH₄HCO₃?
  • Volatile: MS-compatible (evaporates without residue)
  • pH range: 6.5–8.5 (ideal for most organic acids)
  • Shelf life: 4 weeks @ 4°C (make fresh weekly)
  • Concentration: 10 mM optimal (higher = ion suppression in MS)

Common Mistake: Using old buffer (>1 week room temp) = pH drift + microbial growth → ghost peaks.

Gradient Problem From The Lab

Rt shift between days (±0.3 min)

Every morning the first 5 injections have Rt 8.2 min. Then 8.5 min. Then 8.2 again the next day. Why?

Our Gradient Strategy

  • Initial hold 0–2 min @ 5% B — sample adsorbs on the head
  • Ramp 2–15 min do 95% B — linear, curve 6 (Empower)
  • Final hold 15–20 min @ 95% B — elute strongly retained
  • Re-equilibrate 20–23 min back to 5% B + 5 col.volumes

Häufig gestellte Fragen

Dla API (active pharmaceutical ingredient) typowo 98-102% label claim. Dla 2-hydroxybenzoic acid (CAS 69-72-7) sprawdź: (1) USP monograph jeśli istnieje, (2) kompendium pharmacopoeia wewnętrzna, (3) ICH Q6A dla specyfikacji nowych substancji. Related substances ≤0.10% per ICH Q3A.

Prep Mistakes That Ruined The Run

Eksport chromatogramu do raportu

Your boss wants a PNG of the chromatogram for a presentation. You only have ChemStation with a .ch file. How to get from .ch → PNG?

Sample Prep Protocol

  1. Dissolve 10 mg of sample in 10 mL of mobile phase (initial composition)
  2. Sonikuj 5 min → vortex 30 s
  3. Filtruj 0.22 μm PTFE (nie PVDF — adsorbuje!)
  4. Transfer 1 mL do HPLC vial z septum PTFE/silikon
  5. Przechowuj 4°C max 48h

Why Filter 0.22 μm?

Particles >0.22 μm clog the column inlet frit. Pressure rises +50 bar per 100 injections. Column lifetime drops from 2000 to 500 injections. Filter cost: 2 PLN. Column cost: 1800 PLN.

Echte Pannen von Chemikern — was passiert ist, was geholfen hat und was zu vermeiden ist.

Peak tailing ruined my results

Anna K., PhD student, Warszawa 2024-03 Poziom 3/5
Was ist passiert:

I ran the method exactly as written. Main peak Tf = 2.8 (should be <1.5). Integration impossible. I repeated it 6× — always tailing.

💡 Lekcja:

Causes: (1) buffer pH 8.2 instead of 7.0, (2) 2-month-old buffer (bacteria!), (3) C8 column instead of C18. Fix: fresh buffer pH 7.0 + switch to C18 → Tf 1.2, Rs 1.9→2.3.

Why am I not seeing any peaks?

Student MSc, UW 2024-10 Poziom 2/5
Was ist passiert:

You injected the sample, you wait 23 min and... a flat line. Anxiety is rising.

💡 Lekcja:

Wavelength 254 nm does not work for most carboxylic acids — use 210 nm.
