浩瀚环境空气和废气中甲醇测定聚乙二醇石墨化碳黑填充柱5%Carbowax 20M Carbopack B

本标准规定了测定环境空气、无组织和固定污染源废气中甲醇的变色酸分光光度法。
本标准适用于山西省境内环境空气和废气中甲醇的测定。 当定容体积为5 mL时，方法检出限为1.45 μg，测定下限为5.80 μg。
此法操作复杂，费时费力，效率低下。浩瀚色谱（山东）应用技术开发有限公司,与时俱进，研发填充柱气相色谱法测定环境空气、无组织和固定污染源废气中甲醇，外标法定量，结果满意。

  This standard specifies the chromotropic acid spectrophotometric method for the determination of methanol in ambient air, unorganized and fixed pollution source exhaust gas.
This standard applies to the determination of methanol in ambient air and exhaust gas in Shanxi Province. When the constant volume is 5 mL, the detection limit of the method is 1.45 μg, and the lower limit of determination is 5.80 μg.
This method is complicated to operate, time-consuming, laborious, and inefficient. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times and develops packed column gas chromatography to determine methanol in ambient air, unorganized and fixed pollution source exhaust gas. The external standard method quantifies methanol with satisfactory results.
