Computer aided data processing for carbon, hydrogen and nitrogen determination in elemental analysis

This report describes a personal computer system for processing the data obtained by an elemental analyzer with a differential thermal conductivity. The computer receives the data via a digital multimeter with automatically adjusted sensitivity according to the output level and a GP-IB data bus. The compositions of carbon, hydrogen and nitrogen are calculated and printed in a prescribed form which can be returned to a client, with no labor to calculate the composition from the recorder reading and to rewrite the result on a reporting sheet.
