| (1) | Variants / Options |
| (2) | The HM-1400 TRX extracts sample from the process, removes H2O by condensation inside a cooler and standardizes the result with respect to T and P. |
| (3) | If the stack gas temperature is < 200 °C then a heated sample tube is recommended, because the species HgCl2 is absorbed by surfaces with T < 140°C. |
