Determination of trimethylselenonium ion in urine by ion-exchange chromatography and molecular neutron activation analysis
Journal Article

· Anal. Chem.; (United States)
A method has been developed for the determination of the trimethylselenonium ion (TMSe) in urine by anion exchange-cation exchange chromatography, selectively capturing the TMSe on the cation exchange resin. TMSe recoveries are 91.9 +/- 7.6%. The TMSe fraction is irradiated with neutrons and radioassayed for /sup 77m/Se activity. Various experimental procedures including acid hydrolysis, nitric acid digestion, and HPLC were evaluated in order to optimize the determination. 23 references, 3 figures, 5 tables.
