New SI-traceable reference gas mixtures for sulfur

In this method a highly concentrated mixture is produced by spiking a purified synthetic air (matrix gas) with sf6 gas from a permeation device. The mass loss of sf 6 in the permeation device is observed by a magnetic suspension balance. In a second step this mixture is diluted with matrix gas to the desired concentrations.
