Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a method for quantitative detection of hydrogen, hydrogen deuteride and deuterium hydrogen isotopes. The method uses neon as the carrier gas, and the gas chromatograph adopts a dual-column dual-temperature system. Select 50 The sample temperature is ℃, and the sample is injected through a syringe or a gas injection valve. The sample volume is 0.1-2.2mL. The gas separated by the sample gas by the gas chromatographic column generates an electrical signal through the detector. After the signal is amplified by the preamplifier, The chromatographic workstation records the peak areas of chromatographic peak hydrogen, hydrogen deuteride, and deuterium gas, and uses volume correction factor normalization method or external standard method to determine the content of hydrogen (H2), hydrogen deuteride (HD) and deuterium (D2) to obtain Test results. The characteristics are: the separation effect of hydrogen isotopes is good, the detection sensitivity is high, the detection of deuterium gas purity can reach more than 99.99%, and the high-dose injection of deuterated hydrogen (HD) and deuterium (D2), the peaks do not overlap, thus ensuring high For the quantitative detection of pure deuterium gas, there is no need to prepare standard gas in the detection, which simplifies the operation process and facilitates online detection in the production process of deuterium gas.
