This method is for the collection and analysis of diethanolamine. The sample is collected on a 10% 1-naphthylisothiocyanate (NITC) coated XAD-2 tube. After collection, the sample is desrobed with dimethyl formamide (DMF) and analyzed by high performance chromatography with ultraviolet detection (HPLC/UV).
NOTE: This is a partially validated method.
