In order to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China, protect the environment, ensure human health, and standardize the determination methods of total hydrocarbons, methane, and non methane total hydrocarbons in the ambient air, this standard is formulated. This standard specifies the direct injection gas chromatography method for determining total hydrocarbons, methane, and non methane total hydrocarbons in ambient air. This standard is a revision of the "Gas Chromatography Method for the Determination of Total Hydrocarbons in Environmental Air" (HJ 604-2011).
The on-site rapid monitoring method has played an increasingly important supporting role in emergency monitoring of sudden environmental events. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is researching the rapid determination of non methane total hydrocarbons in ambient air using the GC790 portable catalytic oxidation hydrogen flame ionization detector method. Obtain the detection limit, precision, and accuracy of the method, and compare them with laboratory methods. The results showed that the detection limit of the method was 0.127 mg/m3, the precision was 0.1%~3.6%, and the relative deviation of the standard sample was -0.9%~-0.1%. The method is convenient, fast, and has strong timeliness, which can provide technical support for timely handling of sudden air environmental incidents.
