Machine - Fischerscope XDAL, an indispensable device
Revue FH - 30 April - # 8
Luca Verardo of the TAG Heuer Laboratory is categorical: «The Fischerscope XDAL tests give us a rapid, non-destructive indication of the success of a process or choice of material. It is therefore extremely useful for our routine tests and in particular decorative galvanic coatings, for example on hands, applied chapters for dials or oscillating weights».
The Fischerscope XDAL can measure the thickness of the coating at several points (coating homogeneity test) and can also analyse the nature of the metallic substrate. The result is generally obtained after 30 seconds of analysis.
The Fischerscope also makes it possible to obtain information concerning the nature of alloys, particularly the content of elements subject to restrictions, such as lead or cadmium, to distinguish grades of stainless-steel (304, 316, 4C27A, etc), and to test the fineness of precious alloys. X-ray fluorescence spectrometry is an elemental analysis technique which qualifies chemical elements in a given sample. It cannot however measure light elements (low atomic number Z): measurements of hydrogen, lithium and beryllium are impossible; those of boron, carbon, nitrogen, oxygen and fluoride are difficult. And to measure elements such as magnesium, aluminium, silicon, phosphorus and sulphur, it is absolutely essential to evacuate any air contained in the analysis chamber.
