Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury.
The measurement of total gaseous mercury (THg) is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.
The OPSIS System 400Hg DOAS system is different and provides an accurate analyser that will operate with a minimum of maintanence.
The OPSIS DOAS system is based on a non contact method using an optical path. For the measurement of total gaseous mercury, the gases will pass a dry catalytic converter before entering into the optical path.
Besides the measurements of total gaseous mercury, the same analyser system can measure a large number of other gases required by legislation such as NOx, SO2, CO, CO2, NH3, H2O, HF, and HCl.
The system meets the European EN 15267 and other international standards.
