Bruker Microflex LRF MALDI TOF
This MALDI TOF can be used for the analysis of a broad range
of compounds including small molecules, peptides, proteins, nucleic
acids, and synthetic polymers. The Microflex accepts 96 spot target
plates. The matrix assisted laser desorption ionization (MALDI)
source operates with a 60 Hz nitrogen laser at 337 nm. The instrument
has a mass range of up to 20,000 m/z in reflectron mode or 500,000
m/z in linear mode. Additionally the instrument is capable of mass
spectral imaging. Polytools software is available for the analysis of
Waters GCT Premier GC TOF
This high resolution Time-of-Flight mass spectrometer is primarily used for small organic analytes and low polarity materials. The instrument is equipped with electron ionization (EI), chemical ionization (CI), and field ionization/field desorption (FI/FD) ion sources. This instrument has a mass range up to m/z 800 in EI, CI, and FI modes and up to m/z 4000 in FD mode. Accurate mass measurement (<3 mDa) for elemental composition confirmation is available in EI and CI modes. The GCT Premier employs an Agilent 7890 A gas chromatograph and Agilent 7683 B autosampler in EI, CI, and FI modes.
Waters LCT Premier ESI TOF (OUT OF ORDER)
This high resoltuion orthogonal Time-of-Flight mass spectrometer
provides 12000 FWHM resolution and is the main instrument used to for
accurate mass data aquistion of polar organic and organometalic
compounds from 100-2000m/z. The LCT is capable of fast switching
between positive and negative polarities and has the added ESCi
capability thanks to its multi-mode ionization source.
