Philips Analytical announces the MiniPal 2 bench-top

Philips Analytical's new MiniPal 2 Energy Dispersive XRF desktop spectrometer performs non-destructive analysis of elements from sodium right through to uranium, in concentrations from 100% down to ppm levels.

Successor to the MiniPal Energy-Dispersive X-Ray Fluorescence (EDXRF) desktop spectrometer, MiniPal 2 offers even greater levels of versatility. The instrument's key ingredient is its built-in intelligence. It does with software what other bench-top EDXRF systems do with complicated hardware configurations and filtering. This adds considerable flexibility for fast elemental analysis across the full spectrum of the periodic table. The instrument's unique software approach means that it is the bench-top EDXRF system capable of analyzing virtually the full range of elements with no special accessories or modifications. Since the software is Windows®-based, the MiniPal 2 is also very easy to operate, requiring no expert knowledge for routine analysis - the software takes care of it all.

Powerful software features

For incoming inspection or identification of unknown substances such as metals and its alloys, the MinPal 2 offers a unique standardless-analysis feature. Based on theoretical models and specially-developed algorithms, this allows quick analysis of unknown samples.

Moreover, the MiniPal 2 can analyse other various materials in a form of liquid, powders, bulk solids and surface layers. The software also features an integrated deconvolution function that separates closely-spaced peaks in the spectrum that the system would otherwise be unable to resolve. There is also automatic calculation of theoretical α factors to correct for intensity deviations caused by inter-element effects occurring within the sample during measurements, and an integrated SPC facility.

High-efficiency detector and innovative X-ray tube design

Based on the latest Si-PIN technology, the MiniPal 2's detector combines high efficiency with a resolution better than 255 eV. The detector is thermoelectrically cooled, eliminating all the costs and inconvenience of liquid nitrogen cooling associated with other EDXRF systems. The instrument's X-ray tube allows the use of different target materials to avoid possible masking of the sample's spectrum by the spectrum of the tube. It comes with a rhodium target as standard, with chromium, molybdenum and tungsten target materials being available as options.
