One conditioning step in extractive analysis of process and emissions gases is reliable, constant reduction of humidity in the sample gas. The condensate this produces results in sometimes considerable washout effect. This can result in inaccurate measurements, particularly in acidic gas components (e.g. SO2). Adding acidic liquids at an appropriate point in the conditioning system reduces the acid solubility by manipulating the pH level in the condensate, ensuring reliable measurements. The EMIDos dosing unit was designed for this specific application.
