WebApr 19, 2024 · GC and GC-MS are routinely used for the analysis of volatile impurities in APIs. In those cases where the prevailing safety-based limits are quite high – ie, 5,000 ppm for class 3 solvents – then it makes sense to use the less sophisticated, more robust GDC-FID or GC-ECD approaches. In contrast, where the safety-based limits are low – ie ...
WebThe HS-GC-FID method is adopted for tests for residual solvents in pharmaceuticals, but GC-MS is effective for confirming any unknown peaks (impurities) detected in such tests. Accordingly, use of the HS-20 and … WebJun 20, 2013 · If so, it could indicate that the generator produces gas with non-favourable impurities for the specific analysis. Impurities in the carrier gas can also cause the chromatogram to display peaks that overlap each other, so that there is no apparent differential. The solution in this case is the same: check for gas purity and system leakages.
WebFor GC, analysis of nitrosamine impurities can be carried out using either headspace sample introduction for a few of the more volatile nitrosamines, or direct liquid injection, which is effective over a wider volatility range. While direct injection may be preferred due to its simplicity over headspace, it also introduces more matrix into the ...
