Energy Dispersive X-ray Fluorescence (EDXRF) spectrometry is a versatile analytical technique that can satisfy both of these needs: it is non-destructive, requires very little sample preparation and can be configured to handle any sample size from a large surface to a few microns. Archaeometry, the application of scientific methods to archaeology, has very similar requirements. Variation in sample type and size may be almost infinite: from a soil sample to a bullet to a microscopic speck of gunshot residue or fragment of glass. The object itself may, however, need to be presented as evidence, so any technique used for this analysis should ideally be non-destructive. Elemental analysis of an object found in the course of an investigation can yield valuable clues to its origin and history. Many branches of science are employed in accumulating forensic evidence, from highly publicized techniques like DNA profiling to pathology, botany and of course chemical analysis. Scientific evidence plays a vital role in today’s justice system: many high profile criminal investigations reach their conclusions almost entirely on this evidence.

This paper describes two such instruments from SPECTRO Analytical Instruments, the SPECTRO xSORT hand-held metals analyzer, the SPECTROTEST mobile emission spectrometer and the portable metal analyzer SPECTROPORT, and their application to the analysis of aluminum alloys. Laboratory analysis is sometimes not feasible or necessary and expensive and can involve unacceptable delays.īut modern mobile and portable analyzers are available that can handle the necessary analyses on site to provide accurate and positive material identification even when used by non-specialist operators. It is therefore in the best interest of the recycler to identify input material and separate the various grades before processing.
Many specialized aluminum alloys have been developed for applications such as aviation and the automotive industry and these command premium prices, both as new material and scrap. There are two major reasons for this: firstly, aluminum alloys are particularly amenable to recycling and can be recycled many times without losing their properties and secondly, huge energy savings are possible as recycling uses only 5% of the energy required to extract and refine new aluminum. Recycling aluminum alloys is beneficial both financially and environmentally and has become a major industry in its own right. SPECTRO FOCUS Aluminum Recycling (PDF, en).Example: its shutter and unique iCAL standardization system allow SPECTRO xSORT to continuously correct for drift - eliminating the need for tedious annual recalibration! A focus on long-term reliability is evident in every facet of their design. SPECTRO xSORT models are optimized for fatigue-free, on-site measurements. They deliver laboratory-quality results in a matter of seconds. SPECTRO xSORT spectrometers are used in the plant, on the jobsite, or in the most challenging field location. At a range of affordable prices, SPECTRO xSORT spectrometers are leaders in their class for a broad spectrum of applications. Simple, user-friendly displays and efficient ergonomics make these instruments extremely easy to use. They offer metals or nonmetals identification in seconds, with innovative technologies and designs that provide repeatable, laboratory-quality results. These energy dispersive X-ray fluorescence devices are recognized for ruggedness and reliability on the job. The SPECTRO xSORT family of handheld ED-XRF spectrometers supplies elemental testing and spectrochemical analysis of myriad materials in widely varying conditions.
