Dräger Tube Pyridine 5/a - PN: 6728651
Dräger Tube Pyridine 5/a (10)
PN: 6728651
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 pyridine and has the following standard measuring range: 5 ppm Measurements: 10
Application Range
Standard Measuring Range: 5 ppm
Number of Strokes n: 20 additional 5 strokes have to be taken in clean air after opening the second reagent ampoule.
Time for Measurement: approx. 20 min
Standard Deviation: ± 30 %
Color Change: white ä brown red
Ambient Operating Conditions
Temperature: 10 to 30 °C
Absolute Humidity: 3 to 15 mg H2O / L
Reaction Principle
Pyridine + Aconitic acid + Acetic anhydride ä brown red reaction product
Cross Sensitivity
Ammonia in the TLV range does not interfere.
Additional Information
Before carrying out the measurement the lower reagent ampoule must be broken and the liquid transferred to the indication layer so that it is saturated. After performing 20 pump strokes, the upper reagent ampoule must be broken. The granular contents must be shaken out of the broken ampoule by gently tapping the side of the tube. The tube must be held vertically with the inlet of the tube up during the 5 additional pump strokes.
