PANalytical's MiniPal 4 energy-dispersive XRF Bench-Top Spectrometer

Almelo, the Netherlands - PANalytical's new MiniPal 4 energy-dispersive XRF bench-top 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 2 energy-dispersive X-Ray fluorescence (EDXRF) benchtop spectrometer, the MiniPal 4 offers even greater levels of sensitivity and versatility. MiniPal 4Featuring features a new silicon drift detector, with currently the highest resolution in this market segment,assuring it demonstrates higher maximum count rates and improved resolution.twice the analytical performance of its predecessors, with higher accuracy and precision and much lower detection limits.

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.

Coupled with its new detector technology, another key ingredient of MiniPal 4The instrument's key ingredient is its built-in intelligence. It runs on a new version of software for MiniPal spectrometers that This addsadds considerable flexibility for fast elemental analysis across the full spectrum of theentire periodic table. The MiniPal 4 software includes a variety of features that simplify application set-up and data handling, such as recalibration, spectra comparison, robust application defaults and extended calibration options, including a full Fundamental Parameter model and Compton ratio correction. 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. Most important of all - the MiniPal 4 is also very easy to operate, requiring no expert knowledge for routine analysis - the software takes care of it all.

MiniPal 4 runs with the latest software version including a variety of features for increased flexibility and ease of use such as recalibration, spectra comparison, extended database formatting possibilities and a host of other enhancements and modifications. Additionally, a Quick Start Guide for the MiniPal simplifying installation and application set-up is now supplied as part of the package.

MiniPal 4 is one of the smallest full-function bench-top spectrometers currently available. With a mass of only 28 kg, it is configured with a 12-position sample changer (with optional sample spinner), a helium gas attachment for liquids analysis and a selection of X-ray tube anodes (Rh, Cr and other on request) for analytical flexibility. Installation and application set-up are further simplified by a Quick Start Guide that is supplied as part of the package.

For incoming inspection or identification of unknown substances such as metals and its alloys, the MiniPal 4 offers a unique standardless-analysis feature. Based on theoretical models and specially-developed algorithms, this allows quick analysis of unknown samples.
Moreover, Tthe MiniPal 4 can analyse various other a variety of materials in the form of liquids, powders, bulk solids and surface layers. MiniPal 4 also offers a unique standardless-analysis feature for inspection or identification of unknown substances such as metals and its alloys. Based on theoretical models and specially developed algorithms, this allows quick analysis of unknown samples.he 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 factors to correct for intensity deviations caused by inter-element effects occurring within the sample during measurements, and an integrated SPC facility.
