A method is described for the trace analysis of glycols, polyols, and hydroxyamines in aqueoue solutions. The samples are concentrated on an appropriate Sep Pak and dried with a stream of extra dry grade nitrogen followed by elution with a dried solvent. This simple but novel procedure permits rapid derivatization in a nonaqueous environment thus eliminating problems associated with the hydrolysis of the derivatization reagent.
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.
