Auto injector adapter for gas chromatograph

摘要

A method and apparatus is disclosed for adapting auto injector devices to properly operate in conjunction with gas chromatographs that would previously have been incompatible. The invention consists of metal plates (10, 11, 12, 13) with circular apertures designed for placement over the injection port of the gas chromatograph. The plates are designed to align the chosen auto injector with the injection ports (30) and fix it in place. Also disclosed is the use of firmware to enable proper communication between the injector, the chromatograph, and the analysis and control software.
