Abstract : A new turbomolecular pump and vacuum manifold were added to a chemical and biological mass spectrometer (CBMS). Detection limit measurements on pyridine, toluene, and methyl salicylate are reported for both the unmodified and modified versions of the CBMS. Comparison of pyrolysis-mass spectra of egg albumin showed that the modified instrument spectrum did not match those from unmodified CBMS instruments. The changes in instrument operating parameters and hardware of the modified instrument are described. Four oral presentations have been made on data generated from this contract.
