Determination of Hydrogen Isotope by Modified γ-Al2O3 Micro-packed Column
Modified γ-Al2O3 micro-packed column for hydrogen isotope measurement Details:
Name: High-efficiency modified alumina packed column
Specification: 2m*3mm
Model: MnCL2/γ-AL2O3, 60-80 mesh
Application: Hydrogen isotope determination
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used MnCL2 modified γ-Al2O3 micro-packed chromatographic column to analyze the mixed gas of He, H2, HD, and D2. The results show that the modified γ-Al2O3 column for hydrogen isotope analysis is significantly better than the unmodified γ-Al2O3 column in terms of peak shape, retention time and column efficiency. Under the co
nditions of a column temperature of 77.4 K, a neon carrier gas flow rate of 30 mL/min, and an injection volume of 5-100 μL, the hydrogen isotopes have a good linear relatio
nship and the spectral peaks are symmetrical. The resolution of H2 and HD can reach 0.84, HD, D2 The resolution can reach 1.74, the retention times of H2, HD and D2 compo
nents are 1.07, 1.36 and 2.26 min, respectively, and the RSD is 3%. It is expected to analyze the ternary gas mixture of protium, deuterium and tritium within 4 minutes.
