X-Ray Fluorescence Testing

X-ray Fluorescence TestingThe X-ray fluorescence is a non-destructive process and hence, it is used for applications where there is a need to maintain the integrity of the sample. All raw materials and products such as alloys, solders, sterling silver and gold bearing alloys are first tested in X-Ray Fluorescence equipment. At United, an analysis using XRF is done using three different kinds of XRF equipment where each instrument specializes in measuring a specific combination of metals. A strict quality control on silicon level is maintained using one of these instruments. A preliminary scan of various levels of elements in a refining lot are first determined using the XRF equipment. Solder sheets are scanned for uniform distribution of gold so that each solder piece has the correct amount of gold and other ingredients.
