产品说明
一般描述
In packed columns the carrier gas percolates through the porous bed and separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Metal packed columns are more suitable for long and high carrier gas flow rates to tolerate the elevated pressures. Porapak N are porous polymer beads which helps in providing significantly lower background at the carbon emission line. They are suitable for separating H2, CH4, and CO2.
对于不需要玻璃惰性的低要求应用，应使用经济型的金属柱。该色谱柱具有一般性配置，并可小心将其弯曲以适用于大多数仪器。
应用
Stainless steel coulmns packed with Porapak N and molecular sieve may be used to determine the methanogenic degradation by analysing headspace gas with GC.
