Calculation of Peak Asymmetry 5. As per USP, "data from six replicate injections are used if the relative standard deviation requirement is more than 2.0%". System suitability testing (SST) is required by USP, FDA and EP to check and ensure on-going performance of an analytical systems and methods. Pharmacopeial Forum: Volume No. Expert Committee: (GC05) General Chapters 05. Calculation of the Height Equivalent to the Theoretical Plate (HETP) 6. System Suitability Calculations . Calculation of the number of Theoretical Plates per meter (USP method) 2. They are especially important in the case of chromatographic methods, and submissions to the USP should make note of the requirements under the System Suitability section in the general test chapter Chromatography 621. 1. 31(3) Page 825 Injection Volume (GC, HPLC): May be reduced as far as is consistent with accepted precision, linearity, and detection limits. System suitability test parameters to be established for a particular method depend on the type of method being evaluated. USP29–NF24 Page 2639. area/wt) and then calc the overall RSD for the 6 std injections, doesn't this satify the USP system suitability criterion? See USP <621> when the particle size is changed. Establishing meaningful system suitability criteria for chromatography procedures are requirements for a valid procedure and compendial and regulatory compliance. 621> is one of the most important USP general chapters impacting about 5000 USP monographs. Its chapter on Chromatography is <621>, found here, and “defines the terms and procedures used in chromatography and provides general information.” Specifically, it explains the allowable adjustments to chromatography systems in order to meet system suitability requirements. USP 36 Physical Tests / 〈621〉 Chromatography1 (2) The chamber is sealed to allow equilibration (satura- ... system suitability. System suitability tests are run each time an analysis is undertaken A guide to guidelines. Calculation of Peak Tailing (USP method) 4. h Calculation of the number of Theoretical Plates per meter (half-height method) 3. Signal-to-Noise definition based on USP <621> Chromatography Chapter (reference USP 38 NF 33, effective 5/1/2015 to 4/30/2016) S/N is calculated as follows: h 2H S/N = where: H = Height of the peak (Figure 2) measured from the peak apex to a baseline extrapolated over a distance ≥ 5 times the peak width at its half-height. Both USP and EP have chapters with recommendations for system suitability tests that are enforced by FDA and EMA. If I use 2 standards and inject them 3 times (total of 6 injections) upfront, calculate the response factor (e.g. USP <621>[2] and European Pharmacopoeia (EP) chapter 2.2.41[3] have both specified requirements for SST for chromatographic analysis to demonstrate that a chromatograph is fit for the analysis it will undertake on the day of analysis. What material can be used for system suitability? The results are reported using the Performance, Performance + Noise and Performance + Extended report styles.
