Dräger Tube Organic Arsenic Compounds and Arsine - PN: CH26303
Dräger Tube Organic Arsenic Compounds and Arsine
PN: CH26303
Application Range:
Standard Measuring Range: Qualitative 0.1 ppm Arsine and 3 mg org. arsenic/m3 are the minimum detectable concentrations.
Number of Strokes n: 8
Time for Measurement: max. 3 min
Standard Deviation: ± 50 %
Color Change: Yellow → Grey
Ambient Operating Conditions:
Temperature: 0 to 40 °C
Absolute Humidity: < 50 mg H2O / L
Reaction Principle:
a) AsR3 + Zn/HCl → AsH3
b) AsH3 + Au/Hg-complex → Au (colloidal)
Cross Sensitivity:
Phosphine and arsine are indicated before the ampoule is broken, but with different sensitivities.
Additional Information:
Arsine is present if a grey ring appears in the indicating layer after performing 8 pump strokes.
If there is no indication, the ampoule must be broken and the liquid transferred onto the indicating layer such that it is completely saturated.
Then an additional eight pump strokes must be performed.
