New Applications for SPME/Capillary GC: Screening for Amphetamines in Urine; Identifying Tobacco Varieties; Monitoring Nitrogen-Containing Herbicides in Water

Bulletin 901A Solid Phase Microextraction/Capillary GC Analysis of Drugs, Alcohols, and Organic Solvents in Biological Fluids Solid phase microextraction is a fast, solventless alternative to conventional sample extraction techniques. In SPME, analytes establish equilibria among the sample matrix, the headspace…

Application Note 83 Fast, Accurate Detection of Amphetamines in Urine, Using Solid Phase Microextraction/ Capillary GC In monitoring methamphetamine and amphetamine in urine, heated headspace SPME offers a 20-fold increase in sensitivity, relative to conventional heated headspace sampling. Correlation coefficients…

Bulletin 922 SPME/GC for Forensic Applications: Explosives, Fire Debris, and Drugs of Abuse Solid phase microextraction is a fast, solventless alternative to conventional sample extraction techniques. In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample,…

Application Note 84 Identification of Tobacco Varieties, Using Solid Phase Microextraction/Capillary GC Sampling the headspace over a tobacco sample by solid phase microextraction (SPME) affords a fast, sensitive means of identifying the variety, through comparison of individual analytes. Figure A.…
