The MS core facility in the Chemistry Department consists of four instruments. A Waters Xevo QTOF is run by staff personnel and provides high resolution, exact mass determination as well as optional MS/MS and SFC separations. A Bruker MALDI Ultra Flex Extreme offers high resolution on large molecules including proteins. A Waters SFC-MS and an Advion CMS offer low resolution walk-up usage for routine unit resolution analysis with either SFC separation or direct injection. MS analysis is available for corporate users.
