The Thermo Scientific 5020i SPA analyzer ensures accurate sampling and complete data capture of particulate laden flow.

After the particulate sample is drawn into the Model 5020i SPA analyzer through a sample inlet, it is then passed through the converter core where sulfate (SO4) is converted to sulfur dioxide (SO2) utilizing the thermal reduction process. The sulfur dioxide is then measured using our well established pulsed fluorescence analyzer technology.

The Model 5020i analyzer SPA increases instrument up time with minimal effort by eliminating the need for batch sampling.

It also gauges changes and spots trends accurately and immediately. To continuously maximize efficiency for the operation at hand the Model 5020i SPA performs direct and automatic measurement of background zero air without the need for purge gas.
