Poster discussing what the ICH Q14 guidelines entail and how AutoChrom can help implement these principles. The poster includes details about the ICH Q14 guidelines and specific details about how tools and features within AutoChrom can help implement ICH Q14 principles.

This application note demonstrates the use of the Agilent 1260 Infinity II Hybrid Multisampler for the analysis of per- and polyfluorinated alkyl substances (PFAS). The Hybrid Multisampler in feed injection mode was used with optimized Feed Speed for the sample injection to trap and enrich the compounds on the column. This avoided peak broadening and breakthrough of the early-eluting polar PFAS compounds. The less polar PFAS compounds can be enriched for more sensitive quantification.
