  • On-Site SF Gas Analysis - MBW Calibration AG

    , HF etc. To meet specification, dew point sensors depend on accurate calibration both during production, and use. Calibration drift can be significant, so regular calibration is essential to maintain reliable results. Chilled mirror hygrometers are based on the physical principal of condensation formation on a temperature controlled surface.

    that finally proved successful was to release the SF6 directly from a SF6 lecture bottle through a 0.006-inch hole in the lecture bottle cap (see fig. 3). The small hole resulted in a fine jet spray of the SF, that mixed well with the mine air. Mixing was further aided by moving the lecture bottle rapidly

    In this method a highly concentrated mixture is produced by spiking a purified synthetic air (matrix gas) with SF6 from a permeation device. The mass loss of SF6 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.
