FlexStream™ Secondary Dilution Module (FlexSD)

Description

KIN-TEK Analytical's FlexStream Secondary Dilution Module (FlexSD) is an accessory that increases the operational range of a FlexStream permeation tube system. When used with a base module, it introduces a second, controlled dilution stage to the primary gas stream. This allows for the generation of significantly lower final gas concentrations, extending down to parts-per-billion (ppb) or parts-per-trillion (ppt) levels. The exact concentration achieved is determined by variables such as the permeation tube's emission rate and the flow rates set by the mass flow controllers in both the primary and secondary dilution paths. This capability is particularly valuable for creating trace-level calibration standards or ultra-dilute test atmospheres in analytical applications.
