Multiple Stage High Resolution Mass Spectrometry Instrumentation
Abstract
After careful review and testing of several commercially available high resolution, tandem mass spectrometers, the University of Colorado has purchased a model 7070EQ-HF from VG Analytical, Inc. Total cost of the instrument was $415,000 of which 200,000 was provided by grant number AFOSR 83- 0314 from the Department of Defense - University Research Instrumentation Program. The instrument has now been delivered and is being installed in space that was specifically renovated by the University as a new mass spectrometry laboratory. The instrument consists of a high resolution first stage with a forward geometry (electrostatic sector followed by magnetic sector) and a quadrupole second stage which is preceded by a reaction cell. Sample inlets include several probes and a gas chromatograph. Ionization options include electron impact (EI), chemical ionization (CI), alternating CI/EI, and fast atom bombardment. A sophisticated data system is used for mass spectrometer operation, data acquisition, and data interpretation. (RRH)
