Municipal drinking water and waste water facilities all around the world need to analyse water for a wide range of regulated contaminants, many of which happen to be polar, such as inorganic anions and cations. Traditionally, these contaminants have been analysed using ion chromatography with conductivity detection. The requirements for lower reporting levels mean that water testing laboratories need more selective and sensitive analysis techniques, such as ion chromatography-mass spectrometry (IC-MS).

In this on-demand presentation, we look at several water analysis methods routinely performed by drinking and wastewater facilities, from common anion and perchlorate determinations, to the analysis of disinfection byproducts, such as haloacetic acids (HAAs), bromate, and ionic pesticides. Depending on throughput needs, and contaminant type, we discuss recommendations for the best type of IC-MS for each application: from a single-quadrupole IC-MS dedicated to the analysis of perchlorate, to more selective triple-quadrupole IC-MS/MS. Method aggregation and consolidation are shown to easily offset the higher initial purchasing cost of the more selective and sensitive instruments.

By viewing this on-demand presentation you will learn...

  • how to select the instrument based on the analyses the lab performs
  • how to save time and money through method aggregation and consolidation
  • how to reduce the cost-per-sample and reduce tedious sample prep with the modern IC-MS instrumentation                                                

This presentation is suitable for...

  • Municipal water labs managers and scientists
  • Environmental lab managers and chemists
  • Lab purchasing agents and buyers estimating instrument ROI
