Gas analyzer BGA244

The BGA244 Binary Gas Analyzer quickly determines the ratio of gases and vapors in a binary mixture. It's ideal for a host of applications including gas concentration monitoring, vapor concentration monitoring, binary gas blending, PSA (pressure swing adsorption), helium recovery, ozone purity, MOCVD gas monitoring, 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 —Nearly 500 pre-calibrated gases In addition, the BGA244 can lower the cost of ownership. Most applications don't require any zero or span gas calibration, reducing both installation and maintenance costs. See (Tech note—Comparing Thermal Conductivity Analyzers with the BGA244) 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 %.
