This method is used for the determination of ethylenediamine, diethylenetriamine, and triethylenetriamine. The sample is collected on a 1-naphthylisothiocyanate-coated XAD-2 sorbent tube. After collection the sample is desorbed in 2 mL dimethylformamide (DMF) and analyzed by HPLC with UV detection.
The working range of the method for DETA is 0.05 to 150 mg/m³ for a 10-L air sample. The working range of the method for TETA is 0.08 to 160 mg/m 3 for a 10-L air sample. The working range of the method for EDA is 1 to 130 mg/m 3 for a 10-L air sample.
This method is the result of evaluation of OSHA Method #60 for DETA, EDA, TETA.
NOTE: This method replaces NIOSH Method P&CAM 276.
