Drager Short Term Detection Tubes - Nickel Tetracarbonyl 0.1/a (Pack of 9)
These Drager short-term detection tubes are for Nickel Tetracarbonyl (0.1/a). They detect a range of other substances including Iron Pentacarbonyl and Nickel Carbonyl.
Please note they have a shelf life of 2 years and come in a pack of 9 tubes.
Short-term detection tubes require the use of the Drager Accuro Gas Detection Pump. Click here to buy this product.
- Hard-to-reach and on-the-spot measurements can be carried out using the tubes, pump and accessories
- Obtain measurements within 10 seconds to 15 minutes (depending on the type of tube)
- Pre-entry checks, confined space entry, variations in concentration levels in the workplace and contamination of breathing zones are possible applications which may use tubes

|a) Ni(CO)4 + I2 --> NiI2 + 4 CO
b) NiI2 + Dimethylglyoxime --> pink colored complex
|Iron 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 recognised by decoloration of the indicating layer even before the reagent ampoule is opened.|
|After performing the required 20 pump strokes the reagent ampoule must be broken and the liquid carefully drawn onto the indicating layer using the pump.|
