Five purge bubblers at the Mercury Research Laboratory. Preparing purge bubblers for sample analysis. Purging inorganic mercury on to a gold-coated bead trap. Chemically treat (reduce) the sample, purge it from the sample solution, capture onto gold coated bead trap, desorb the analyte on the instrument which has AFS detection.
