Abstract

A gas analyzer system for analyzing and monitoring samples of compressed or ambient gas such as breathing air and informing the user as to the results of the sample'"'"'s gas purity without the gas sample having to be physically transported to an accredited laboratory. The system comprises a gas analysis module situated at a user facility for receiving the contents of a gas sample and detecting gas impurity characteristics, and a server situated at a remote certification and monitoring center and electrically coupled to the gas analysis module via a bi-directional communications link such a computer network connection. The remote server receives and stores the gas purity characteristics in the form of computer-readable gas impurity data obtained from the analysis module. The server compares the impurity data with the contents of a database containing threshold gas purity parameters and provides the test results to the user facility by electronic messaging.
