AutoBlend Complex Mixtures Generator

The AutoBlend Complex Mixtures Generator is a multi-channel, computer-controlled blending system that uses permeation tubes to create trace concentration gas mixtures. Component concentrations can be independently varied, rendering the instrument ideal for sensor testing and methods validation. During operation, the permeation tubes that are installed in each channel emit a small, precisely known flow of each component compound. The computer system controls the proportionate combination of flow from the various channels with a precisely controlled carrier-gas dilution flow to form the mixture for each channel. Mixtures containing up to 48 compounds can be dry or humidified in nature, and delivered at pressures up to 20 psig. The concentration of each component in a mixture is traceable to NIST through physical standards.
