Achieving low-level detection of benzene in beverages with an automated headspace vial sampler
Eight commercially available beverage samples were selected for low-level detection of benzene by static headspace analysis. This study will use the Teledyne Tekmar HT3 Automated Headspace Vial Sampler to analyze parts per trillion (ppt) levels of benzene in beverages. A GC/MS system will be employed in full scan/SIM mode for separation and detection of benzene, as well as other volatile compounds.
The HT3 was capable of detecting 0.05 parts per billion (ppb) of benzene in the samples with excellent linearity from 0.05 to 20 ppb. The 0.05 ppb quantitation level achieved is 20 times lower than the European benzene drinking water requirement of 1 ppb.
