A simple and accurate bench top method Is presented for the analysis of chemically bonded reversed-phase (C^C6, C18) HPLC packing materials, based on HF digestion and analysis by capillary or packed column GC. Bonded silanes of six carbon atoms or more are analyzed by hexane extraction and GC, while the more volatile trimethylsilane "capping" silanes are analyzed by a headspace technique. Overall analysis
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
