Dräger Tube Phosphine 0.01/a - PN: 8101611
Dräger Tube Phosphine 0.01/a (10)
PN: 8101611
Dräger-Tubes™ are used together with a Dräger tube pump for measurements of gases, vapors and aerosols, usually in air, and are one of the classic methods of gas analysis. This Dräger-Tube is used for the detection of phosphine and has the following standard measuring ranges: 0.1-1 ppm 0.01-0.3 ppm Measurements: 10
Application Range
Standard Measuring Range: 0.1 to 1.0 ppm / 0.01 to 0.3 ppm
Number of Strokes n: 3 / 10
Time for Measurement: approx. 2.5 min / approx. 8 min
Standard Deviation: ± 10 to 15 %
Color Change: yellow ä red
Ambient Operating Conditions
Temperature: 2 to 40 °C
Absolute Humidity: < 20 mg H2O / L
Reaction Principle
PH3 + HgCI2 ä HCI + Hg-phosphide HCI + pH indicator ä red reaction product
Cross Sensitivity
Arsine is indicated with different sensitivity. Up to 6 ppm sulfur dioxide or 15 ppm hydrochloric acid does not interfere, but higher concentrations cause plus errors. More than 100 ppm ammonia leads to minus errors. 30 ppm hydrocyanic acid does not affect the 3 stroke test, but with the 10 stroke test minus errors of up to 50 % can occur.
