A combination of headspace large volume single drop extraction and solid phase microextraction permitted attainment of high sensitivity by transferring an overall large mass of analytes into a gas chromatograph.
There are many methods of analysis at the disposal of a forensic scientist for the routine analysis of controlled drug substances. However, the main objective has always been to introduce new, versatile techniques with high efficiency, selectivity, and excellent precision.
The equilibrium rather than exhaustive nature of headspace single drop microextraction (HS-SDME) and headspace solid phase microextraction (HS-SPME) allowed concurrent sampling of volatile organic compounds (VOCs) on the same sample...
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.
