Identification of methyl tert-butyl ether in human blood with chromatography-mass-spectrometric method

Бесплатный доступ

This article details the applying of GC-MS for accurate identification and study the fragmentation of ionized molecules of methyl tert-butyl ether in human blood. Basing on the reception of mass spectrum of ions of methyl tert-butyl ether the structure, molecular weight, elemental composition of a molecule of methyl tert-butyl ether are defined. The characteristic ions (primary and confirming ions) of methyl tert-butyl ether are detected and the chromatographic retention time is determined. In the process of performing of identification of methyl tret-butyl ether in a blood sample on the mass spectrogram the peak is set which is the result of overlap of several individual peaks of the compounds-isomers with the identical retention times: 2- methylpentane, methyl tert-butyl ether and 3-methyl pentane. To eliminate low resolution in the studies two consecutive capillary columns were used.
