一般說明

玻璃棉由短玻璃纤维制成,本质上不易燃。它被广泛应用于船舶、汽车、空调管道和给水管道的保温材料。此外,它还被用作音乐厅、演播室和电影院的吸声材料。最重要的是,它对人类没有致癌性。[1]
羊毛塞通常用于GC进样口衬管中,以改善样品蒸发,和/或防止非挥发性物质进入色谱柱。它们还可用于填充的气相色谱柱、溶剂解吸管、热解吸管、以及吹扫捕集阱,以保留吸附床。

應用

硅烷化玻璃棉气相色谱填充柱可在试验过程中用于测定和收集食用油中的挥发物。[2]

Questions

1–2 of 2 Questions  
  1. Do I need Product No. 20410, Silanized Glass Wool for my packed column application?

    1 answer
    1. Most applications, except for nonreactive compounds such as hydrocarbons, PAHs, etc., need to be done using silanized glass wool.  If untreated glass wool is used and the compounds are reactive, such as basic compounds, the compound adsorbs to active silanol sites. This can result in peak tailing, loss of sensitivity on the low end and poor linearity.  For free acids, use acid-treated glass wool.
