Analyze sewage sludge with the ARL QUANT’X EDXRF Spectrometer

Sewage sludge is a byproduct of domestic sewage and waste water treatment. Due to the nature of the physicochemical process involved in waste water treatment, sludge tends to concentrate heavy metals and other harmful constituents present in waste water. In this application note, Thermo Fisher Scientific illustrates how the ARL QUANT’X™ EDXRF Spectrometer is ideally suited to screen and monitor the heavy element content of sewage sludge. An easy, straightforward calibration using fundamental parameters and pure element compounds offers a fast semi-quantitative analysis method with very little sample preparation required. The silicon drift detector (SDD) allows for excellent element sensitivities and the multiple primary beam filters offer optimal background control.
