Introducing the BGA244 — a gas
analyzer that measures the ratio of
two gases in a mixture, or the purity
of a single gas, with better than 0.1 %
The speed of sound in a binary gas
mixture depends on the temperature,
heat capacity, and the molar mass of
the mixture. By precisely measuring
the speed of sound and temperature,
and knowing the thermodynamic
properties and molar masses of the
gases, the BGA244 determines the exact
composition of gas mixtures.
The BGA244 provides a hundred fold
improvement in stability, accuracy and
resolution over thermal conductivity
analyzers. It also lets you choose from
500 gases, enabling you to measure
thousands of mixtures.
The BGA244 operates without
lasers, filaments, chemical sensors,
optical sources, separation columns,
reference gases, or reagents, and runs
It’s ideal for research and industrial
applications where precision gas
measurements are needed.
