Precise Coating Thickness by X-ray Fluorescence (XRF)

Coating Thickness XRF Analyzer for PCB Testing

An excellent example of XRF Technology in use for coating thickness applications, the Maxxi series from Oxford Instruments is a customizable system that allows an end-user to build the machine they require and obtain the best price-to-performance ratio.  The system comes standard with a hi-resolution Si-PIN detection system, which provides optimum performance for the most difficult coating applications - but that can be optioned into a lower cost Proportional Counter Detector for when only basic coating measurements are required.  Additional options include collimator packages, x-ray tube design (W or Be targets), sample positioning, and more.

While the Oxford Instruments line of x-ray fluorescence offers additional units with proportional counter detectors, the benefits that the Maxxi chamber design provides may make it the best fit for a clients interest.  Benefits include the larger interior chamber and optional programmable/motorized XY stage.
