Organic Arsenic Compounds & Arsine Detection Tubes (3 mg org. arsenic/m3)

For short-term measurements more than 160 Draeger-Tubes are available to measure the so-called spot concentrations of specific gases. A wide range of different gases and vapours can be detected and measured, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.

Cross SensitivityPhosphine and arsine are indicated before
the ampoule is broken, but with different
Additional InformationArsine is present if a gray ring appears in
the indicating layer after performing the first
eight pump strokes.

If there is no indication, the reagent ampoule
must be broken and the liquid of the ampoule
transferred to the indication layer so that it is
completely saturated.

An additional eight pump strokes must be
performed to detect the presence of
organic arsenic compounds.
