New Modular Gas Standards Generator

KIN-TEK’s (USA) new FlexStream Modular Gas Standards Generating System offers total flexibility for creating precision gas mixtures. The FlexStream System dilutes the emission from permeation or diffusion tubes with an inert gas (typically nitrogen or zero air) to create trace concentration – ppm, ppb, and pptr – gas mixtures. An internal microprocessor is used to set the operating mode and adjust dilution flows to achieve desired concentrations. 

The FlexStream System expands the capabilities of the microprocessor controlled, stand-alone FlexStream Permeation Tube Unit. A FlexStream System can have one to six modular channels.  Modules available include Standard Permeation units, a Gas-Fed permeation unit for high-pressure gases like methane or oxygen, a Secondary Dilution unit to expand the concentration range, and a Humidity Generator to humidify mixtures. Mixtures containing up to 48 components are possible. The FlexStream can use all Kin-Tek Trace Source permeation and diffusion tubes.

The FlexStream System can also be controlled remotely from a PC. Using an external PC allows remote control of the FlexStream, uploading methods (recipes) that can run automatically, and evaluating ‘scenarios’ to aid in setting up the unit to create specific mixture concentration ranges.
