  Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses pulse discharge helium ionization detector (PDHID) gas chromatography to determine ammonia in hydrogen. By examining the peak conditions of different chromatographic fillers, suitable chromatographic columns and conditions were selected and determined. The relative standard deviation of the method repeatability is less than 2%, and the detection limit is less than 10 × 10-9 v/v, which can meet the determination of trace ammonia in hydrogen used in hydrogen fuel cells
