| Abstract: | This writing adopts Gas Chromatography to Detendnation of the Formaldhydein Air. The Formaldehyde is changed into the Methanol by the Trasform Tube. Then wesurvy the height by FID and detendng the amotmts of the Formalehyde in the samPle bynormaliztion method. This method is simper. farster and senstivity than others. The limit ofdetection is 7. 5× 10μg /mL. Linear scope rangeS from 1. 5 ×10(-3)μg /mL to 4. 8 ×10-hμg/mL. The coefficient of varlation is 3. 77% (n=10). The recovery range is from102. 0% to 104. 0%. |
