STACK EMISSIONS

Emissions are pollutants of either gas or particulate (dust) in the ambient air occurring as a result of the combustion of fuel or other materials. Lear Siegler source a wide range of instrumentation for our clients individual monitoring needs. Whether you require dilution of your sample, direct extraction, in place measurement or open path measurement we have a product for you.

Dilution extractive products clean the sample of process emissions to be transported for analysis by dilution ensuring a cleaner dryer gas. The cleaning and sample conditioning is in one and therefore there is far less maintenance on your instrumentation.

Direct Extractive technology draws the raw sample of process emissions for analysis from the stack and it is transported to the analyser for analysis. In most cases some conditioning of the sample is required to remove water vapor and particulate matter. This process ensures an unchanged and non altered gas sample.

In-situ or in place measurement happens at the source of your process emissions and the sample never leaves the stack. In effect, this is also remote sensing, because the sample never touches any sampling apparatus. This will ensure a rapid response in measurement and a rapid response in your process control.

Open Path monitoring is based on the principle of transmitted infrared light to detect and quantify the gas of interest. You can be assured that sample taken when using open path monitoring is very representative of the whole sample.

The Mercury Freedom System utilises advanced cold vapor atomic fluorescence technology which enables provision of continuous sample measurement with no additional gases or accumulations required.  This is true, real-time monitoring which required no batch processing and high sensitivity allows for greater dilution ratios.
