- Applications for use include variations in concentrations in the workplace, contamination of breathing zones, pre-entry checks and confined space entry
Specification
| Application Range | |
| Standard Measuring Range: | 0.02 to 0.2 ppm Discoloration compared to color comparison tube. |
| Number of Strokes n: | 25 |
| Time for Measurement: | approx. 20 min |
| Standard Deviation: | ± 30 % |
| Color Change: | white --> orange |
| Ambient Operating Conditions | |
| Temperature: | 15 to 30 °C |
| Absolute Humidity: | < 20 mg H2O / L |
| Reaction Principle | |
| a) Pyridylpyridinium chloride + NaOH --> Glutaconaldehyde sodium oletate b) 2,4-TDI (also for 2,6-TDI) + HCI --> Aromatic amine c) Aromatic amine + glutaconaldehyde --> orange reaction product |
|
| Cross Sensitivity | |
| Other isocyanates are not indicated. No interference by: 5 ppm aniline 10 ppm benzylamine 5 ppm toluene 20 ppm benzene Mercaptans also discolor the indicating layer. |
|
| 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 changes color to yellow. Next, the upper reagent ampoule must be broken and the liquid transferred to the indication layer, so that it returns to a white color. After performing 25 pump strokes wait 15 minutes before evaluating the indication. | |
