The M1 MISTRAL as a spectrometer for the accurate analysis of bulk and coating samples using small spot X-ray fluorescence analysis (Micro-XRF). Operating in ambient air, all elements from aluminum (Z=13) upwards can be analyzed with the Rh-target version. The analysis range with the W-target version starts from potassium (Z=19). This enables the analysis of a wide range of different sample categories, including metals, alloys and metallic multi-layer systems.
Even large samples with sizes up to 100x100x100 mm³ can be analyzed. Excitation and fluorescence radiation detection takes place from above, without sample contact. This allows measurement on differently shaped samples, from flat surfaces of some GMF products to the most intricately shaped piece of jewelry.
The M1 MISTRAL is equipped with a high brilliance micro-focus X-ray tube, which is capable of producing a high excitation intensity, even if the smallest available collimator is used to produce a spot size of a mere 100 µm. Measurement locations can be pinpointed exactly, using the combination of video microscope and the optional motorized X-Y-Z stage.
