Trace Nitrogen in Argon Analyzer
Specific Model Information
This instrument relies on the known spectrum emitted from a
plasma discharge from a distinct gas mixture of variable composition at
or near atmospheric pressure. This instrument cannot be used for
analysis on any gas or gas mixture other than nitrogen in argon or a
mixture specified at the time of purchase. Specific filters carefully
chosen and tested at the factory have been installed for the particular gas
mixture. Using this instrument to analyze any other gas mixture will
result in serious error. Consult the factory for additional information for
gas analysis not specified at the time of purchase.
