After the POCIS are collected from the field sites, the discs inside are removed in the lab and processed. Rebecca Plummer, a chemist with HRSL, processes the matrix inside the discs to prepare it for analysis on a liquid chromatograph tandem quadrupole mass spectrometer (LC-MS/MS). This new method is faster and requires laboratory processing which allows for more samples to be processed.
