Special feature: Perspective. Host–guest chemistry in the mass spectrometerJournal of Mass Spectrometry - Tập 30 Số 7 - Trang 925-939 - 1995
Marco Vincenti
AbstractThe study of host–guest chemistry in the gas phase has been pursued systematically only in the last 5 years, after sporadic interest in the 1980s, despite extensive investigation of this chemistry in the condensed phase and the success encountered in several fields of application. Most gas‐phase studies have been performed under the controlled conditions th...... hiện toàn bộ
Determination of paraquat and diquat in human body fluids by high‐performance liquid chromatography/tandem mass spectrometryJournal of Mass Spectrometry - Tập 39 Số 10 - Trang 1147-1152 - 2004

AbstractParaquat (PQ) and diquat (DQ) in human whole blood and urine were analyzed by high‐performance liquid chromatography/tandem mass spectrometry (HPLC/MS/MS) with positive ion electrospray ionization (ESI). The compounds were extracted with Sep‐Pak C18 cartridges from whole blood and urine samples containing ethyl paraquat as an internal s...... hiện toàn bộ
