Photoplate interpretation system employing a visual display monitor for spark source mass spectrometry analyses
Technical Report
·
OSTI ID:5446958
An interactive automated data acquisition/analysis system for processing spark source mass spectrometry photoplates is described. Automated reading of the photoplates was accomplished by interfacing a general purpose microcomputer to a densitometer that was previously used for manual photoplate interpretation. Data acquisition is computer-controlled by custom software. A video terminal provides display of peak profiles and peak locations as the plate is scanned, thereby facilitating operator intervention during the selection of data to be recorded. Subsequent calculations are carried out within the microcomputer using the Hull equation, and the analysis is output on a line printer. 24 references, 12 figures, 3 tables.
