Application

Chloroacetic acid may be used as an analytical reference standard for the analysis of chloroacetic acid in:
  • Natural waters by ion chromatography-electrospray ionization-tandem mass spectrometry (IC-ESI-MS/MS).
  • Bottled water, swimming pool water, and both source water and drinking water from a drinking water facility by high performance IC-ESI-MS/MS with multiple reaction monitoring (MRM) detection.
  • Tap water by gas chromatography-mass spectrometry (GC-MS).
  • Drinking water by GC coupled to halogen-specific detector equipped with MS operating under the electron ionization mode.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
