Series 2000 Multi-Component Gas Mixer
Available from Environics Inc.
The Environics® Series 2000 Computerized Multi-Component Gas Mixer automatically blends and dilutes gases to generate precise gas calibration standards, create gaseous atmospheres or produce gas mixes for analytical research or production purposes. The Series 2000 dynamically produces complex mixes containing up to eight(8) individual component gases in a balance gas. Each component concentration may be independently varied in response to user commands. The Series 2000 can produce gas concentrations from percent levels to ppb for single or multi-point calibration of gas chromagraphs, process gas analyzers, mass spectrometers, FTIR's and other gas analytic devices.
The Series 2000 consists of a single chassis supporting up to nine (9) mass flow controllers, a serpentine pre-mix zone and a zero dead-space final mixing zone. Gas wetted surfaces are electro- polished 316 stainless steel. Seals are gas-compatible elastomer. User interface includes a backlit 80 character by 25 line liquid-crystal display and membrane keypad.
The instrument's mass flow controllers are factory calibrated using a primary flow standard traceable to the United States National Institute of Standards and Technology (NIST). The calibration data consists of an eleven-point comparison of commanded versus actual flow with linear interpolation between the points.
