The triphenylamine azo compounds were successfully characterized by matrix-assisted laser desorption-ionization time of flight mass spectrometry(MALDI-TOF MS).
Tetrachloroethane in air was collected by activated carbon,desorped with carbon disulfide,separated by GDX-103 chromatography column,and detected by flame ionization detector.
Desorption chemical ionization mass spectrometry of twelve metallohematoporphyrin complexes has been investigated under DEP condition using mixture of tetramethylsilane and methane as regent gas.
Widely used in air purification for hospital mortuary, zootomy room, police corpse inspection room etc. Low sorption pressure with high speed, complete and fast sorption relief.
