The CAI GPA 2000 Gas Purity Analyzer is capable
of providing the end user with a continuous gas
measurement or, if desired, the ratio of
gases in a binary gas mixture based on
the physical properties of the gases present.
The speed of sound in a gas depends on the temperature, the specific heat and the molar mass of
the gas. By precisely measuring the speed of sound via
a resonant acoustic cell, together with the temperature
of a gas mixture and knowing the thermodynamic
properties and molar mass of the gases present,
the GPA 2000 can determine the composition of a gas
mixture with an accuracy of approximately 0.1%.
The GPA 2000 is equipped with data on nearly
500 gases characterized by a wide range
of concentrations. This gas information is easily
selected from the front panel or remotely controlled via a digital
interface, enabling over 50,000 different mixtures
to be measured. Gases can be added to data
tables that can user-defined gas mixtures that can be
treated as a gas species.
