A method for determination of diethylolamine(DEA) and methyl-diethylolamine (MDEA) in absorption solution of acid gases by capillary gas chromatography is described. It was operated at 220 ℃ on a DB-WAX 30 m×0.53 mm capillary column. The detector temperature was 350 ℃. Triethylene glycol was used as the internal standard and the correction factors of DEA and MDEA were 1.321 and 0.728，respectively. The relative standard deviation is 1.1%～5.3%(n=6) with 98.07%～105.5% recovery. This method has the advantages of accuracy， rapidity and simplicity.
