Reaction Principle |
Carbon disulfide reacts with primary tube to produce intermediate product which changes the indicator of analyzer tube to yellow. |
||
| Coefficient of Variation | 10% (for 50 to 400 ppm), 5% (for 400 to 1600 ppm) | ||
| Shelf Life | 3 Years | ||
| Corrections for temperature & humidity |
Temperature correction is necessary | ||
| Store the tubes at cool and dark place. | |||
