The
mass spectrometry facility is housed in a 1000 sq ft laboratory
located in the UMSL Research Building (R003). In addition to the
three mass spectrometers described below, there are areas for data
processing, instrument maintenance, parts storage and sample preparation. The instrumentation is used for support of research and teaching.
Hewlett Packard GC/MS System Model 5988A
For routine mass spectral analysis following capillary column
gas chromatographic (GC) separation with:
- Electron impact (EI) and chemical ionization (CI) capabilities
- Positive and negative ion detection
- An extended-mass quadrupole
- A solids probe
- Work
stations for data processing and library spectral searching
JEOL
