Alicat Scientific, Tucson, Ariz, has updated its Gas Select firmware to include a library of up to 130 preloaded gases, referenced to NIST Prop 9. The firmware comes standard on all Alicat mass flow meters and controllers and now includes a new Composer module, designed to provide greater customization and flexibility for accurate mixed gas measurement. With the utility, users have the ability to quickly program and store personalized medical gas compositions directly on Alicat equipment.

Using the device’s integrated digital display, users can define gas compositions to 0.01% for up to five constituent gases. In addition, up to 20 gas mixes can be created and stored simultaneously on each device, enabling monitoring and control of custom gas mixtures for calibrating lung diffusion and blood gas analysis equipment. Personalized gas compositions can also be added or deleted quickly, allowing the instruments to adapt to variations in future flow needs.
