INSTRUMENT NAME: AppliedBiosystems / MDS Sciex QSTAR XL Quad - Time-of-Flight Mass Spectrometer

INSTALLATION DATE: December 2002

OPERATOR: Julian Whitelegge, Frederic Halgand, Sara Bassilian, Puneet Souda, and Lori Shoemaker

SYNOPSIS: Our AppliedBiosystems / MDS Sciex QSTAR XL is our newest mass spectrometer arriving as a late Christmas present on the 26th of December 2002. With a mass range of 5 to 40,000 m/z, mass accuracy of 5 ppm, and resolution of 10,000 FWHM this instrument adds significant capabilities to our collection of instruments. We now have the capability of true MALDI MS/MS using the oMALDI source. This capability had proven itself with true MS/MS spectra [as opposed to PSD] on peptides in limiting amounts. With the nano-spray source installed we routinely run LC/MS/MS proteomics experiments, especially those involving Dr. Julian Whitelegge’s plant photosynthesis membrane proteins. Recent software patches have also solved many of the initial software bugs. The QSTAR is a vital addition to our already wide array of instruments.
