Nickel Tetracarbonyl Detection Tubes 0.1/a (0.1 - 1 ppm)

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 SensitivityIron pentacarbonyl is also indicated by a
brownish discoloration, however, with less
sensitivity. Measurement of nickel tetra
carbonyl is not possible in the presence
of hydrogen sulfide of sulfur dioxide, since
the reading is suppressed. Such a
disturbance can be recognized by
decoloration of the indicating layer even
before the reagent ampoule is opened.
Additional InformationAfter performing the required 20 pump
strokes the reagent ampoule must be
broken and the liquid carefully drawn
onto the indicating layer using the pump
