EDX 3600B Energy Dispersive X-ray Fluorescence Spectrometer

X-ray fluorescence (XRF) is a powerful analytical technique used in a wide variety of industries to determine the elemental composition of various materials. XRF analyzers are widely recognised as a means for accurate, rapid, and non-destructive testing.

The Skyray EDX3600B is a high-end energy dispersive XRF spectrometer (EDXRF) with a large sample chamber which supports most sample sizes. The system comes with a vacuum pump for light element detection and a helium injection system for liquids analysis. The Skyray EDX3600B is a multifunctional rapid analyzer applicable to a variety of applications (some are listed below).

The system comes with easy-to-operate software suitable for all users. The software highlights all the information a user may require on one screen including elemental spectrum, measurement time, sample image and real-time test results, critical instrument data and more. Furthermore, this system provides a colour camera system for simple sample alignment and viewing. In only 10 seconds the operator can see the main elements contained in a sample. Full results are available after a short additional period.
