A Computer Method for the Calibration of a Photographic Emulsion for Spectrographic Analysis.
Abstract
A computer method to calibrate emulsion-covered glass plates used to interpret densities of lines for quantitative spectrographic work is reported. This method follows a slightly modified ASTM graphic method, which is also described, and allows one to simply input dark and light data points to establish preliminary and emulsion calibration curves. After the curves are established, by inputting percent transmission data pairs for a known or unknown concentration line and an internal standard line, one obtains the relative intensity. The computer method is used on a Hewlett-Packard Calculator 9830-A and a UNIVAC 1108 time-sharing computer. Programs for both computers are included in this report. (Author)
