Large Chamber XRF with XY Stage for Quality Control

Coating Thickness XRF Analyzer for PCB TestingAn excellent example of XRF Technology in use for a wide range of applications, the Maxxi-5 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 Maxxi-5 XRF system comes standard with a hi-resolution Si-PIN detection system, which provides optimum performance for the most difficult coating applications (thin films, etc) - 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 software packages for material identification, bath analysis, and more.

MAJOR BENEFITS: 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.  The programmable XY and mapping functions are helpful for small samples and analysis of populated circuit boards.
