The new FlexStream™ automated Perm Tube System offers total flexibility for creating precision gas mixtures. Mixtures are produced by diluting the miniscule flow emitted from Trace Source™ permeation (or diffusion) tubes with a much larger flow of inert matrix gas, typically nitrogen or zero air. The FlexStream™ is ideally suited for creating trace concentration – ppm, ppb, and pptr – mixtures. The FlexStream™ Base Permeation Unit is small, easily transportable and easily combined with other FlexStream™ modules to form integrated gas mixing systems.
