Pinhole X-ray spectroscope
Benchtop system provides quick, non-destructive determination of elemental composition for jewellery and dental alloys and is also suited to forensic science applications
Spectro Analytical Instruments introduces a new 'pinhole' XRF (X-ray fluorescence) analyser designed specifically to meet the needs of jewellery and dental alloys analysis as well as those of forensics laboratories The new Spectro Midex analyser uses state-of-the-art XRF technology and proprietary beam collimation techniques to ensure the easiest, most accurate measurement results possible within a typical 2-3-minute response time

New dimension in micro X-ray fluorescence analysis
Outfitted with four computer-controlled collimators with diameters from 0.1 to 1.0mm, this instrument is suited to analyses ranging from jewellery to archaeology and forensics
Using a collimated X-ray beam means that the sample itself, or the region analyzed on the sample, can be extremely small.
As a result, composition of irregular surfaces, small metal fragments, and even metallic coatings can be measured quickly, accurately, and reliably.
Spectro Midex spectrometers use an air-cooled, low-power X-ray tube.
The beam excites the elements in the sample, causing them to emit fluorescence radiation that contains information on the quantitative and qualitative elemental composition of the sample.
An advanced semiconductor detector converts the fluorescence radiation into an output signal proportional to the spectral energies emitted.
None of the sample material is destroyed, a significant benefit for forensic and medical laboratories.
