| Abstract: | A method was established for determining the four Formaldehydes including formaldehyde, acetaldehyde, acrolein and acetone. The adsorbents and pre-treatment were tested and parameters were optimized. The good linearities of the four compounds were achieved. The limits of detection of formaldehyde, acetaldehyde, acrolein and acetone were 0. 075 μg/m^3 , 0. 207 μg/m^3 , 0. 715μg/m^3 and 0. 159 μg/m^3 by 12 liters sampling air. The RSD were from 7.5% to 9.7%. |
