Abstract (en)
[origin: WO9321533A1] A calibration reagent of the type including known concentrations of one or more gases dissolved in a carrier vehicle further includes helium dissolved therein. The helium acts to stabilize the concentration of dissolved gases. The reagents are very useful in the calibration of a wide variety of gas analysis equipment and may be readily stored under a wide range of ambient conditions.
