For more than 50 years the employees of Bühler Technologies have been have been developing, manufacturing and distributing components and system solutions in the “Gas Analysis“ and “Fluidcontrol“ divisions.

By specialising in the market niches Gas Analysis and Hydraulics and by offering a complete range of products for each, we have succeeded to become a worldwide leader in both disciplines.

In the chemical industry, petrochemical, biochemical and other industrial fields, production and system safety is dependent upon determining reliable operation and process parameters. In a large number of these applications, gas analysis is the key to safe and efficient control of process flow, environmental protection and quality assurance in many industries, for example in power stations, air separation, sterile production and packaging in the food industry.

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.
