Calibration gas generators are used to mix calibration gasses for techniques such as GC or gas detector calibration and are capable of calibration gas generation at sub-ppm to % gas concentrations. Gas calibration equipment can be utilized to produce single calibration gasses as well as mixing multipoint gas calibrations. Oftentimes meeting requirements for various regulatory bodies such as NIST, gas calibration generators can automate the process of mixing trace concentration calibration gas. For laboratories requiring high ppm or % concentration calibration gas, ensure a sufficient flow rate is offered by the calibration gas generator. Calibration gas equipment typically has onboard screens for user input and to display real-time information, however, certain models also offer additional options such as PC interfacing for control and monitoring.

| Description | Inquire | The EcoFlex™ Permeation System is designed for creating trace concentration gas mixtures. Mixtures are produced by diluting the minuscule flow of vapor emitted by Trace Source™ permeation (or diffusion) tubes with a much larger flow of inert matrix gas, typically nitrogen or zero air. Mixtures The EcoFlex™ Permeation System is designed for creating trace concentration gas mixtures. Mixtures are produced by diluting the minuscule flow of vapor emitted by Trace Source™ permeation (or diffusion) tubes with a much larger flow of inert matrix gas, typically nitrogen or zero air. Mixtures contact only suitably inert materials, Teflon®, coated stainless steel, or glass.
The EcoFlex™ manual system is built on the same readily transportable platform as the microprocessor controlled FlexStream™ Base Module. The EcoFlex™, however, is a simple, stand-alone, non-expandable, single oven permeation system.
The EcoFlex™ holds the Trace Source™ Permeation Tube(s) at a constant temperature and introduces a small controlled flow of dilution gas over the tube. Pure component compound vapor emitted from the permeation tube(s) mixes with this small flow to form a ‘base’ concentration gas mixture. This base mixture then joins a larger main dilution flow to form the final mixture. The mixture concentration is set by adjusting that main dilution flow.
Permeation tubes of various emission rates are available for over 550 compounds. By choosing a tube suited to the application, mixtures having concentration from low ppb to over 1000 ppm can be generated and the concentration can then be adjusted over a 20:1 range. A single permeation tube, for instance, might be used for concentrations from 1 ppm in 250 cc/min or down to 50 ppb in 5 slpm. Using the mixture immediately after preparation eliminates storage loss....

Application of this principle is meaningful when the moisture content of the background diluent gas exceeds 10 percent of the minimum concentration to be generated. Calibration is based on the change in analyzer response caused by the The Span Pac™ H2O instrument works on a differential principal. Application of this principle is meaningful when the moisture content of the background diluent gas exceeds 10 percent of the minimum concentration to be generated. Calibration is based on the change in analyzer response caused by the addition of a known water vapor concentration from a KIN-TEK Trace Source™ water permeation tube to a flowing stream of the diluent gas. This differential method overcomes the “no zero” problem, and the problem of the background gas affecting the response.
The permeation tube emission rate is certified by the Factory traceable to NIST by gravimetric weight loss over time. This provides a close approximation to a primary standard, even in situations where primary standards are not available.
KIN-TEK takes special care in design, construction and choice of hardware components to minimize errors due to atmospheric contamination and interactions with other materials in the system.
