摘要
随着产业的发展,对超高纯氨的需求越来越大,品质要求也越来越高。因此对于氨气中的杂质控制也更加严格。详细介绍了GC-9560-HG氦离子化气相色谱仪在超高纯氨分析中的应用。该色谱仪可准确测定超高纯氨气中的杂质。
With the development of industry, the demand for ultra high-purity grade ammonia is getting greater and greater, and the need of its quality has become higher and higher. So the impurities of ammonia are detected more strictly. The arti- cle details the application of GC-9560-HG helium ionization chromatograph in the analysis of ultra high-purity grade ammo- nia. Gas chromatography can determine the impurities of ultra high-purity grade ammonia well and truly.
