Direct Quantification of Ammonia and Alkylamines in Aqueous Environments Using Solid‐Phase Microextraction‐Gas chromatography‐Mass spectrometry

open access: yesChemistry–Methods, EarlyView.
Fast and Facile! The use of a solid‐phase microextraction fiber allows direct sampling of aqueous solutions of ammonia for quantification using gas chromatography‐mass spectrometry (GC‐MS). The technique is insensitive to the presence of organic cosolvents or transition‐metal ions, making it particularly well suited for the analysis of catalytic ...
