Automated signal recording system for the Perkin-Elmer 240 elemental analyser
Abstract
An automated signal recording system for the Perkin-Elmer 240 elemental analyser is described. The construction of the system involves two main areas, an electronic interface (between the instrument and the digital voltmeter-printer) and a microswitch and cam assembly (to supply signals from the elemental analyser). Illustrative results are reported for selected standard compounds.
