THERMO Electron, represented in Australia by Lear Siegler Australasia , has released the 5020 sulphate particulate analyser (SPA).
It offers continuous, real time sampling and analysis of total sulphate in ambient air. The automatic measurement of background air reduces labor and cylinder gas costs.
The 5020 SPA converts SO4 to SO2 using a thermal reduction technique. SO2 is then analysed using pulsed fluorescence spectroscopy. The result is a continuous analyser producing data points every 10 seconds. Isokinetic extraction of the sample assures complete capture of the particulate laden flow.
Not only is the SPA less complex to set-up and operate than other sulfate analysers but it offers the same software environment as other Thermo gas analysers. The SPA can also be used with industry-standard inlets to assure consistency with other established particulate methods.
