HJ 1072-2019 Determination of Pyridine in Water Quality Headspace/Gas Chromatography Method
This standard specifies the headspace/gas chromatography method for determining pyridine in water.
This standard is applicable for the determination of pyridine in surface water, groundwater, domestic sewage, and industrial wastewater.
When the sampling volume is 10.0ml, the detection limit of the method is 0.03mg/L, and the lower limit of determination is 0.12mg/L.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a direct water sample high-performance gas chromatography method for the determination of pyridine in drinking water sources using PEG20M and OV-624 dual columns The advantages of simple preprocessing, no use of highly toxic reagents, and fast analysis speed The relative standard deviation is not greater than 6.9% (n=7), and the recovery rate is 89% -108% Experimental results have shown that it has the advantages of simple and fast operation, environmental protection and safety
