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 that can be achieved inside
a mass ... 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 standard. The separation of PQ and DQ
was carried out u... hiện toàn bộ
