The BGA244 Binary Gas Analyzer quickly, continuously, and non-invasively determines the ratio of gases in a binary mixture, or checks the purity of a single gas.
It's ideal for semiconductor processing, research, and industrial applications where precise measurements of gas mixtures are necessary.
The BGA244 operates without lasers, filaments, chemical sensors, optical sources, separation columns, reference gases, or reagents, and runs virtually maintenance-free.
The speed of sound in a gas depends on the temperature, specific heat, and the molar mass of the gas.
By precisely measuring the speed of sound and temperature in a gas mixture, and knowing the thermodynamic properties and molar masses of the gases, the BGA244 determines the composition of gas mixtures with an accuracy of about 0.1 %.
Operating Modes
The BGA244 has three basic measurement modes:
Binary Gas Analyzer, Gas Purity Analyzer, and Physical Measurements Analyzer.
In Binary Gas Analyzer mode, two gases for analysis can be chosen by name, formula, or CAS number on the touchscreen display.
When operating in Gas Purity Analyzer mode, the user simply selects the single gas of interest.
In Physical Measurements mode, the BGA244 reports the speed of sound, temperature, and gas pressure.
This extends the BGA244's utility beyond gas analysis, for example, to enable the measurement of thermodynamic properties of gas mixtures.
In each mode, the BGA244 displays large numeric readouts of the parameters being measured. In the Binary Gas Analyzer and Gas Purity Analyzer modes, a needle graph shows the user-defined operating range in green, and higher and lower limits in red.

Comprehensive Database
Thermodynamic and molar mass data for more than 250 gases have been tabulated in the BGA244, enabling the instrument to measure tens of thousands of mixtures.
Gases can be added to the data tables, as can pseudo-gases (user-defined gas mixtures which are treated as one gas species).
