Portaspec® for Multi-Element Sequential Analysis


Model 2501XBT

Portaspec WDXRF is capable of performing multi-element sequential analysis in the range of Ti to U and is ideal for measuring coating weights of both chrome and titanium pretreatment.

The Bench Top Portaspec is similar to the original Model 2501 Portaspec X-Ray Spectrograph. It contains a rotating goniometer that allows the user to analyze up to five elements, preset sequentially one at a time. The elemental range is from element #22 Titanium to element #92 Uranium. An easy load two-position sample holder is an integral part of the instrument configured for analyzing liquids, powders, solids and thin films. Samples are changed at the open end of the holder allowing a sample to be analyzed while one is being loaded.

The Portaspec is operated by a PC Notebook Computer, complete with Windows®-based preinstalled Software.

Other Bench Top Portaspec versions available are Fixed Channel Single Element, Dual Element and Multi-element for sequential analysis.
