With applications including sensor evaluation, analytical methods development and validation, and gas filter testing, the AutoBlendTM from Kin-Tek is a multi-channel, computer controlled, gas blending system for creating complex test gas mixtures.

Six independently controlled channels using permeation or diffusion tubes add trace concentration components to matrix gas. Each channel can contain up to eight compounds in disposable permeation tubes.

Two additional (and optional) dynamic headspace modules add higher concentrations of common mixtures, or low volatility substances to the test mixture.

A secondary dilution feature allows the system to be used for a wide concentration range from high parts-per-million (ppm) down to low parts-per-billion (ppb). An optional humidification module is used to add humidity to the final mixture.

Kin-Tek notes that a key feature of the AutoBlend™ is that the output from each channel can be adjusted independently so that the concentration of each trace component group can be set independently. This allows for automated operation of statistically designed factorial test programs, making the AutoBlend™ an ideal tool for sensor testing and qualification, catalyst sensitivity research, odor research, and similar applications requiring a range of complex test gas mixtures.
