Span Pac H2O-R moisture-standard generators create known calibration standards for trace moisture in reactive gases, including chlorine and HCl. They employ the standard additions technique, in which a small flow of dry inert gas flows over a permeation tube to create a base moisture standard. Measured amounts of the base mixture are then added to a flow of the reactive gas to create the standard. Permeation tubes cover concentrations ranging from <10 ppb to >100 ppm. Multi-point calibrations over a 400:1 range are easily achieved at any concentration level. They can be used in moisture monitor calibration, moisture probe validation, filter capacity testing, and adsorption testing.
