A trial period in the hydrogen and the oxygen-containing molecular sieves purity analysis after Wuzhong, but found that this method has some drawbacks. Its performance is: initially activated zeolite molecular sieve effect, hydrogen peak, peak oxygen away near; new music sieve, sieve oxygen peak tailing column after a period of time; and soon completely covered peaks of hydrogen oxygen peak, causing no critical analysis oxygen content. When the company resolved to argon carrier gas oxygen content measured hydrogen, nitrogen, hydrogen content and purity, resulting in hydrogen cover peak oxygen peak shortly after the problem with the molecular sieve column, and then solve the over with helium as the carrier gas when analyzing costs high. Jinju sieve, sieve, sieve by new Shanghai there are new molecular sieve Limited. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new molecular sieves, and you hand in hand into the brilliant, for a better future!
