Analyze liquid hazardous waste fuels with ARL QUANT’X EDXRF Spectrometer

Liquid hazardous waste is an industrial waste typified by mixtures of solvents, oils, paints and pigments which may pose a potential hazard to human health or the environment when improperly disposed of. Before incineration, it is usually required by governmental regulations to screen such liquid hazardous waste fuel (LHWF) for the presence of toxic and/or volatile elements above certain concentration levels. In this application note, Thermo Fisher Scientific highlights the capability of the ARL™ QUANT’X Spectrometer to monitor 11 elements over a wide concentration range. Sample preparation using graphite as described in ASTM D5839 offers a fast and straightforward method to deal with the typical non-homogeneity of LHWF samples. A 60 second analysis time per condition under air yields detection limits of 5 ppm or less.
