This method is for the determination of triethylamine and trimethylamine frrom workplace air samples. The sample is collected on 10% phosphoric acid coated XAD-7 tube. The sample is shaken with 1:1 methanol/deionized water followed by a 1:4 solution of 1N NaOH/methanol and then analyzed by GC/FID (flame ionization detector).
