Kin-Tek Laboratories Inc. Modular Gas Standards Generator 491M

KIN-TEK is proud to announce the development of a new, modular Gas Standards Generator, the Model 491M, for blending gas standards in the laboratory. A unique feature of this unit is its capability of generating concentration ranges from sub-ppb levels to over fifty percent, from pure compounds, using single step dilu- tion. The Model 491M can generate gas mixtures from permeation tubes, diffusion tubes, and compressed gas cylinders. It can also humidify the gas standard or house special analyzer interface controls. The inter- changeable modular features of the instrument allow the user to customize it to fit specific applications. For low concentration mixtures, permeation tubes are used to generate a very small, precisely known flow of the component compound. This permeate flow is then mixed with a much larger flow of a matrix (or diluent) gas to form the trace concentration mixture. Using this method, concentrations from low ppb to over 1000 ppm can be prepared directly from pure compounds. Each 491M cabinet can house up to 3 modules in one standard 19” cabinet. One module is a “Base” module with a permation oven, mass flowmeter for dilution flow measurement, and dilution flow controls. The other modules to select from are: 1) a module for blending high concentration mixtures (% levels) directly from a compressed gas cylinder; 2) a gas standard humidification module; 3) a module for analyzer interface con- trols; 4) a gas control module for converting the standard permeation oven to one which can use gas filled permeation tubes; 5) additional liquid filled permeation tube oven modules.
