GC /CI (iso-C_4H_(10) ) MASS SPECTROMETRY OF TMS-DERIVA- TIVES OF T-2 TOXIN AND ITS METABOLITES

摘要

SIM and SRM are two kinds of more sensitive scan modes than the whole range scan mode. SRM is very powerful in removing the chemical interference, so it is more selective and has higher s ratio than SIM. Comparing El and CI(iso-C_4H_(10)) mass spectra of TMS-derivatives of T-2 toxin and its metabolites, El mass spectra are not very characteristic, because most of the fragments are in the low m/z ratio range. On the other hand, CIMS are more featured and so are more important than EIMS in detection and determination of such type of toxins.
