Application Range | |
Standard Measuring Range: | 0.5 to 5 ppm |
Number of Strokes n: | 20 |
Time for Measurement: | approx. 5 min. |
Standard Deviation: | ± 10 to 15 % |
Color Change: | white --> yellow |
Ambient Operating Conditions | |
Temperature: | 10 to 40 °C |
Absolute Humidity: | 3 to 15 mg H2O / L |
Reaction Principle | |
2 R-SH + Pd2+ --> Pd(RS)2 + 2 H+ | |
Cross Sensitivity | |
Higher molecular weight alkyl mercaptans (e.g. propyl- and butylmercaptans) are indicated with approximately the same sensitivity. 1,000 ppm ethylene, 2,000 ppm carbon monoxide and 200 ppm hydrogen sulfide do not affect the indication. Hydrogen sulfide discolors the pre-layer black. |
