ENVIRONMENTAL monitoring specialist Quantitech says it has experienced a surge in demand for its Gasmet portable FTIR emissions analyser, the DX4000. “We believe that 
this instrument is now the only portable FTIR with MCERTS certification, and this is driving demand for both instrument rental and sales,” says Dominic Duggan.
The Gasmet DX4000 portable FTIR gas analyser is typically used in stack emissions monitoring, comparison measurements, catalytic process control and other applications where multiple gas compounds need to be accurately monitored in a hot and humid sample gas. The corrosion resistant sample cell is heated to 180 °C, which ensures that the sample stays in the gaseous phase even with high concentrations of moisture or corrosive gases.
The DX4000 comes equipped with easy-to-use Calcmet™ software, which can display the concentration results in ppm, mg/Nm3 or Vol-%, and all measurement data can be stored for further analysis.
Typical configuration for the instrument enables the simultaneous measurement of H2O, CO2, CO, NO, NO2, N2O, SO2, NH3, CH4, HCl, HF and different VOCs. However, additional gases can be added without any hardware changes, says the company.
