scope:
Specifies a technique for the continuous production of calibration gas mixtures from pure gases or gas mixtures using capillary devices in single or multiple combinations (gas dividers). Single capillary systems can be used to provide gas mixtures where the minor component is in the range of volume fractions from 10-8 to 0,5. The relative repeatability of this technique is approximately 2 %. This application is used in industrial gas mixing panels for the production of specific gas atmospheres.
