一般描述

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。
当采用较高的载气流速时,基本上使用的是由不锈钢而制成的填充柱,因为它们可以承受更高的压力。不锈钢柱通常先用稀盐酸洗涤,然后用水及随后的甲醇、丙酮、二氯甲烷和正己烷洗涤,以除去任何腐蚀产物和痕量的润滑剂。[1]

应用

填充在不锈钢柱中的Carboxen 1000可在厌氧室中用于产甲烷古菌的研究。[2]

Questions

  1. Could you elaborate on the process of bending the column to accommodate different instruments for the product Metal Packed GC Column (General Configuration), SKU 12390-U?

    1 answer
    1. Stainless steel 1/8" GC columns can be adjusted to fit a particular instrument, provided that the tubing is not kinked or bent excessively. If reshaping is necessary, it should be done slowly and carefully, especially for columns packed with carbon-based material, like Carboxen-1000, or any column containing carbon-based material that may fracture if the tubing is bent too far. Fractured packing, regardless of type, can lead to active sites that may adsorb specific types of compounds.
