Analysis of Organics in the Environment by Functional Group using a Triple Quadrupole Mass Spectrome from the analysis of influent to a waste water treatment plant obtained by both GC/MS and triple quadrupole mass spectrometry are compared. In the triple quadrupole method, both knowns and unknowns are characterized, detection limits are at the 10–100 ppb level, and the total analysis time per sample is typically only 25–30 min.

Oliver Baum,Werner Reutter,Felix Bermpohlrmal- and reversed-phase separation systems in HPLC and the use of HPLC as a preparative separation before detailed analysis by HRGC and HRGC/MS. Several examples of such applications are presented including determinations of polycyclic aromatic hydrocarbons, oil hydrocarbons, alkyl phenols and alkylphenolpolyethoxylates.
