Mass Spectrometry PittCon '95

Pittcon 1992 — Abstracts

The Consortium on Automated Analytical Laboratory Systems (CAALS) has been formed with interested parties from the private sector and other government agencies at NIST to foster the creation of automated chemical analysis systems that will improve the quality of analytical data, facilitate the entire analytical process, and promote the standardization and transfer of analytical methods, while p...

Pittcon Abstracts (1991)

Different forms of metals and metalloids have varying degrees of toxicity in biological systems. Because of this, there has been an increase in the research focused on the speciation of metals at trace levels. Plasma mass spectrometric detection of hydride species has been established as a viable technique for the determination of these species at trace levels. One problem with the determinatio...

Identification of aflatoxins by quadrupole mass spectrometry/mass spectrometry.

MS/MS daughter experiments were recorded for aflatoxins B1, B2, G1, G2, M1, M2, and aflatoxicol, using 3 ionization modes. Daughters were recorded from the molecular ion (M+) using electron impact ionization (EI). Daughters from the protonated molecules (MH+) were recorded in the positive ion mode and the daughters from the molecular anion (M-) were recorded in the negative ion mode using chemi...
