Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses DC550 packed column gas chromatography to determine the content of phosphine, phosphorus trichloride, and phosphorus trichloride in hydrogen gas used in polycrystalline silicon production. A coated sampling cylinder is used to collect hydrogen gas used in polycrystalline silicon production, and an FPD flame photometric detector is used to detect the content of phosphides in the sample gas. The sampling time is short, the introduction of impurities is reduced, and the obtained sample gas has good representativeness and improves work efficiency.
