Determination of Non-Methane Hydrocarbons in Ambient Air by Canister Sampling-Transfer Air Bag Injection-Gas Chromatography
The method for non methane hydrocarbons determination in ambient air by canister sampling-transfer gasbag injec-tion-gas chromatography was established.The calibration curve,blank experiment,detection limit,sample stability experi-ment,trueness and precision verification results show that the correlation coefficient of the calibration curve is greater than 0.999 4,the detection limit is 0.04 mg/m3,and the relative error and relative standard deviation of the measurement results of low,medium and high concentration quality control samples are less than 4.00% and less than 4.00%.The method has the advantages of low detection limit and good accuracy,and the sample analysis shows that the method is suitable for the de-termination of non-methane total hydrocarbons in ambient air.
