We present the reliable and accurate quantitative analysis of contaminants at the pg/mL level in drinking water using the Thermo Scientific EQuan MAX Plus LC-MS system coupled to the Thermo Scientific TSQ Endura triple quadrupole mass spectrometer. Excellent reproducibility was shown for the target compounds in tap water using 1 mL injections at 0.37× maximum effluent concentration.

The fast separation of five herbicides was performed using the Thermo Scientific Acclaim 120 C18 column with a run time of less than five minutes with MS detection.

The Thermo Scientific HPLC system is applied with the Thermo Scientific Accucore 2.6 µm RP-MS column for the fast analysis of a range of urea herbicides. The separation was achieved in less than four minutes with UV detection showing this column can provide good baseline resolution of the analytes with low operating pressures.

The Thermo Scientific HPLC system is applied for the determination of uron herbicides. The separation is performed on a Thermo Scientific Accucore RP-MS HPLC column, with UV detection at 240 nm.

The Thermo Scientific HPLC system is applied for the analysis of uron herbicides. The separation is performed on a Thermo Scientific Hypersil GOLD HPLC column, with UV detection at 254 nm.
