A novel method for quantification of decabromodiphenyl ether in plastics without sample preparation using direct insertion probe – magnetic sector high resolution mass spectrometry

We report a rapid, efficient analytical method for detecting Brominated Flame Retardants (BFRs) in plastic materials using direct insertion probe with double focusing magnetic sector high resolution mass spectrometry.

Volatile organic compounds analyzed by direct insertion probe mass spectrometry

A modified approach for analyzing volatile organic compounds through standard direct insertion probe mass spectrometry is presented. With aluminum oxide or silica powder packed in a capillary tube, the sample’s evaporative loss in a high vacuum instrument chamber is significantly reduced and the retention time is increased accordingly. With this technique, organic compounds with lower boiling points (e.g., 2-butanol at 99 °C) can be readily detected and analyzed.
