一般描述

玻璃棉由短玻璃纤维制成，其性质上是不易燃的。它被广泛用作船舶、汽车、空调管道和供水管道中的隔热材料。此外，它还用作音乐厅、工作室和电影院的吸音材料。最重要的是，它对人类无致癌性。
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。

应用

硅烷化玻璃棉气相色谱填充柱可用于测量和收集食用油中挥发性物质的实验过程。

其他说明

已经过硅烷化 ，可用于一般用途

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Do I need Product No. 20411 Silanized Glass Wool for my packed column application?

    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.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.

Parahydrogen is a potentially significant source of hyperpolarization. However, a heat exchanger at an ultralow temperature, which is normally sustained wastefully using liquid nitrogen, is essential for the generation of hyperpolarized parahydrogen. In order to cut down on the use
