Diffusion tubes are an inexpensive, do-it-yourself way to dynamically blend trace concentration gas mixtures for a large number of common solvents.
KIN-TEK’s Trace Source™ configurable diffusion tubes extend the range of compounds that can be used to include subliming solids and viscous liquids. These tubes have a removable reservoir that allows filling with the capillary removed, so the component compound can be any consistency. Additionally, a variety of pre-configured and tested capillaries can be interchangeably fitted to the reservoir adjust the range of concentrations obtainable.
Multiple tubes can be used simultaneously in the FlexStream™ Automated Gas Standards Generating System to create multi-component gas mixtures.
