Abstract

The analysis of phosphonic acids in a spiked tap water has been investigated by capillary electrophoresis-mass spectrometry (CE-MS) and liquid chromatography-mass spectrometry (LC-MS) as part of the Third Official Proficiency Test of the Organization for the Prohibition of Chemical Weapons. The useof a non-volatile electrolyte (5 mM sorbic acid/ammonia, pH 6.5) in CE anda volatile mobile phase(water/0.1 v/v trifluoroacetic acid/acetonitrile) in LC achieves the baseline resolution of studied phosphonic acids. Tandem-MS detection analysis allows an accurate identification of these solutes by screening their characteristic fragmentations.
