How to Analyze Chloroacetic acid s

July 24, 2013

Q. Do you know of a method to analyze for chloroacetic acid [on eBay or Amazon]s (mono, di, tri)? Levels would be 1 to 100 µg/l or so.
Solution likely to be 2-4 gpl NaCl.

Thank you in advance.

A. Gas chromatography, after derivatization with diazomethane. An extraction step might be required as well.

You can likely adapt the "Standard Methods..." procedure for herbicides in water to this analysis.
