Detection limits of Pb in various materials/components measured using the FISCHERSCOPE® X-RAY XDV®-SDD compared to the limit values of various regulations.
Table 1 illustrates the detection limits for Pb in various materials using the X-ray fluorescence method. While direct measurement is possible for Pb, for Cr and Br only total concentrations – not the exact concentrations of the harmful compounds – can be determined. Compliance is established when the total concentration is below the limit values, otherwise additional analysis methods must be employed. The required detection limits can also be met for other heavy metals as well, such as Cd, Hg, As, and Ba.
Your local contact person for FISCHER products will be happy to assist you in selecting a suitable X-ray fluorescence instrument for measuring very small concentrations of harmful substances – FISCHERSCOPE® X-RAY XDV®-SDD, XAN® 150 with SDD detector, or XDAL® with PIN detector.
