​​Bruker micrOTOF-Q II Quadrupole Time-of-Flight Mass Spectrometer

Bruker micrOTOF-Q II Quadrupole.jpg

This instrument is a high-resolution accurate mass quadrupole-time-of-flight mass spectrometer, with electrospray, nanospray, atmospheric-pressure chemical ionization, and atmospheric-pressure photoionization sources with a mass range of 50-3000 m/z, an average resolution (m/Δm, width at 10%) of 8,000, and the capability to perform collision-induced dissociation (CID) tandem mass spectrometry experiments, up to MS2. This instrument is housed in laboratory space permitted to handle low-level uranium-containing radioactive samples. This instrument is connected to a Waters H-Class Plus Ultra High Performance Liquid Chromatorgaph (UHPLC), for chromatographic separation of samples prior to mass analysis. This instrument is primarily used for identification and quantification of organic unknowns, although it can also be used for cluster studies.​​​​

​​​​This instrument is a two-dimensional gas chromatograph with a time-of-flight mass spectrometer detector.The mass spectrometer has an electron impact ionization source, unit mass resolution, and a mass range of 10-1000 m/z. This instrument can be equipped with a CDS Analytical pyrolyzer for analysis of solids. This instrument is excellent for identifying organic components in very complex mixtures, and is adequate for quantification.​






​​Other Gas-Chromatography Instruments​

​The facility has several single dimension gas chromatographs with mass spectrometry detectors. Most have single quadrupole mass analyzers with electron impact ionization, but one has a triple-quadrupole mass analyzer with electron impact, and positive and negative chemical ionization sources. The facility also has numerous gas chromatographs with flame ionization, barrier ionization, electron capture, flame photometric, nitrogen-phosphorous, and thermal conductivity detectors. Most instruments are configured for liquid analysis, though some are dedicated for gas and non-condensable analysis. These instruments are used for characterization of organic unknowns, and quantific​​ation measurements.​​​​​
