Description

Analysis Note Easily determine water content in solvents with high aromatic content with one easy GC method. It is very common to  screen for aromatic impurities and moisture in solvents, but two different methods generally need to occur. Most commonly, a Karl Fischer method for water determination, as well as a GC method for aromatic impurities that can take up to an hour analysis time. With a combination of the Watercol 1910 column from MilliporeSigma, and the GC/BID from Shimadzu, this can be done in less that 20 minutes with one column and fantastic results. The BID shows a great response for aromatics and water with a stable baseline.
