BGA244 Binary Gas Analyzer 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 a host of applications including binary gas blending, PSA (pressure swing adsorption), helium recovery, ozone purity, dopants and carrier gases, and general research 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. Traditionally, thermal conductivity based analyzers, or Katharometers, have been used to make these sorts of measurements. These analyzers operate by comparing the thermal conductivity of the measured gas to that of a reference gas.

The BGA244 offers dramatic improvement in performance over thermal conductivity based gas analyzers. -Ten times better accuracy -Thousand times better stability -Tremendous flexibility with nearly 500 pre-calibrated gases In addition, the BGA244 can lower the cost of ownership. Virtual Dj Pioneer Cdj 2000 Skin. Most applications don’t require any zero or span gas calibration, reducing both installation and maintenance costs.

See (Tech note – ) for more details on the advantages of the BGA244. Principle of Operation 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.

Gases can be chosen by name, formula, or CAS number on the touchscreen display or over the computer interfaces. 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. Limits can be set in all modes of operation. High and low limits can be defined for gas composition, gas purity, speed of sound, temperature, and pressure. Limits can generate “events”, setting or clearing relays.

Comprehensive Database Thermodynamic and molar mass data for nearly 500 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). Remarkable Accuracy The accuracy of the gas composition result depends on the difference in the speed of sound between the gas species. Shown below are the typical composition errors for several gases mixtures. For measurements requiring greater accuracy, a REL to the dominant gas species can be performed to remove most of the systematic errors. With this, an accuracy of 10 ppm is possible (depending on the gas species).

In many cases, the pressure is stable and can be entered on the front panel or over the computer interfaces. For applications that have varying operating pressures, an external pressure gauge can be easily connected to one of the analog inputs.The BG244 operates over a pressure range that extends from a few psi up to 150 psi. Heaters, Relays, I/Os & Power. The BGA244 comes equiped with several multipurpose analog I/Os, two user-defined event relays for process control or alarms, and cavity heaters for temperature regulation and condensation prevention. There is an input for an external 24 VDC power supply.
