We will discuss USP General Chapter <621>, including which analytical parameters may be adjusted to achieve passing SST results. • USP requires system suitability (SST) to be periodically demonstrated. 1. While the USP … System suitability test is an essential part of HPLC & GC methods The United States Pharmacopeia (USP) Chromatography General Chapter states: “System Suitability Tests are an integral part of gas and However in Chapter 621 of the USP [1] there is a list of adjustments than can be made to existing methods without re-validation, of course that system suitability still has to pass. They are used to verify that the resolution and reproducibility of the chromatographic system are adequate for the analysis to be done. That is to ensure that the complete testing system including instruments, electronics, reagents, column & analyst is suitable for intended application. In August 2014, the United States Pharmacopeia and the National Formulary (USP-NF) put into effect new guidelines to “allowable adjustments” in its Chapter <621> (USP37-NF32 S1). 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. However, the user should verify the suitability of the method under the new conditions by assessing the relevant analytical performance characteristics potentially affected by the change (see section System Suitability under Chromatography <621>). This is a big mistake as both the United States Pharmacopoeia (USP) as well as the European Pharmacopoeia (Ph. System suitability tests are run each time an analysis is undertaken As described in The United States Pharmacopeia (USP) guidelines, suitability testing is a concept which holds that the electronics, equipment, specimens, and analytical operations constitute a single analytical system, which is amenable to an overall test of system Amid several other critical discussions, this training program will detail FDA and international requirements for system suitability testing; SST in comparison with equipment qualification and quality control sample analysis; critical parameters for SST in EP and USP; recommendations for implementing the updated <621>; and developing an SOP for system testing. for chromatographic methods check USP <621> or Ph.

System Suitability Testing (SST) is commonly used by laboratories to ensure that the complete analytical system (including instrument, reagents, columns and analysts) is suitable for the intended application. The main system suitability parameters are 1. System suitability testing (SST) is required by USP, FDA and EP to check and ensure on-going performance of an analytical systems and methods. System Suitability Calculations . In accordance with the Rules and Procedures of the 2005–2010 Council of Experts, USP has postponed indefinitely the implementation requirement of text pertaining to System suitability, Detection sensitivity requirements published in the USP 29–NF 24, which becomes official on June 1, 2006. As such, it … Precision 2. Calculation of Peak Asymmetry 5. System suitability testing is an integral part of many analytical procedures including mass spectrometry analysis. 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. For example USP allows a change in column length of + 70%. Eur.) Rather, the use of System Suitability Samples (SSSs) or resolution test mixtures containing both main components and expected impurities is required. Eur. Calculation of the number of Theoretical Plates per meter (half-height method) 3. System Suitability Rs between B and C > 2.0 4.8 4.0 %RSD multiple injections <2.0 0.1 0.1 Savings Achieved Analysis time per injection 10 min 5 min (- 50%) Solvent used per injection 10 mL 6.96 mL(-30%) ... ¾ USP <621> also allows translation of the flow rateto a higher linear velocity to System Suitability Formulae and Calculations System Suitability Formulae and Calculations The HP ChemStation uses the following formulae to obtain the results for the various System Suitability tests. … • All standards are measured with 3 replicates and the average is … As per USP, "data from six replicate injections are used if the relative standard deviation requirement is more than 2.0%". Most critical parameters for SST in EP and USP Contents of the updated USP chapter < 621> Recommendations for implementing the updated < 621> Developing an SOP for system testing Criteria for SST timing within a sequence of sample runs Using software for automated system suitability control USP 36 Official Monographs / Tacrolimus 5257 • LABELING: If a test for Organic Impurities other than Proce-Chromatographic system dure 1 is used, then the labeling states with which Or-(See Chromatography 〈621〉, System Suitability.) • SST standards use color coded shapes to ensure proper placement in auto sampler rack. The system suitability test is used to verify that the chromatographic system is suitable for the intended analysis or not. The tests are based on the concept that the equipment, electronics, analytical operations and samples to be analyzed constitute an integral system that can be evaluated as such.

In the recent revisions of USP <621> and EP <2.2.46>, the modification of parameters is allowed only when the chromatogram improvement is still within the stated system suitability factors. If I use 2 standards and inject them 3 times (total of 6 injections) upfront, calculate the response factor (e.g. Other pharmacopoeias should be consulted if required, however, the US Pharmacopoeia recommends that to determine system suitability % RSD, 5 replicate injections if the % RSD is 2.0 or less and if the % RSD is greater than 2.0, six replicate injections are recommended. Chromatography General Chapter <621> contains a list of allowed adjustments to chromatographic systems. USP29–NF24 Page 2639. • QbD1200 is designed to make this process convenient. Calculation of the number of Theoretical Plates per meter (USP method) 2. Other sources for referencing about the System Suitability Testing are the USP (United States Pharmacopeia) and the ICH (The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use).
