Electronic Instruments is a leader in advanced instruments for the process, aerospace, power and industrial markets. AMETEK consists of two operating groups: Electronic Instruments and Electromechanical. is a leading global manufacturer of electronic instruments and electromechanical products with over 12,000 colleagues at more than 100 manufacturing locations and 100 sales and services centers worldwide. From its foundation in 1979 until today, SPECTRO has delivered more than 30,000 analytical instruments to customers around the world.ĪMETEK, Inc. SPECTRO’s products are exemplified by unique technical capabilities that deliver measureable benefits to the customer. As a unit of AMETEK’s Materials Analysis Division, SPECTRO manufactures advanced instruments, develops the best solutions for strongly varying applications and provides exemplary customer service. SPECTRO is among the world leading suppliers of analytical instruments for optical emission and X-ray fluorescence spectrometry. Because sometimes stylistically different silver jewelry composed of similar materials are found at different locations, it is even possible to use the archaeometallurgical investigations to trace antique trade routes. ![]() It is possible to reconstruct the manufacturing processes and to identify the period of time in which objects were created by investigating the precious metal contents and determining the by-elements. A SPECTRO xSORT already has been used to examine antique objects found in Turkey. XSORT BELMONT PORTABLEMobile Instrument Uses in ArchaeometallurgyĪn interesting secondary application for the portable SPECTRO xSORT is the scientific study of archaeological gold and silver treasures. ![]() The SPECTRO xSORT also has an optional integrated video camera so the measuring point can be exactly determined. This is important if the value of a piece of jewelry is to be determined or if the jewelry is to be further marketed as second-hand jewelry and not just be thrown into the recycling bin.” “Best of all, the pieces of jewelry do not need to be ground and scratched for measurements with the XRF instrument. “Our instrument, however, shows the precious metal content to both parties,” emphasizes Dirk Wissmann, who is responsible for the XRF spectrometer product line at SPECTRO. The precious metal content of typical gold alloys can be determined well enough with traditional touchstone testing (acid test), but this procedure requires someone with experience – and the seller has to believe the collector. For precious metal recycling, the handheld spectrometer offers security for both buyer as well as seller. Operation of the instrument is simple measurements are conducted at the press of a button. In addition, the XRF instrument’s non-destructive measuring makes it suitable for applications in archaeometallurgy. ![]() The inexpensive, portable instrument is able to identify the gold and silver content in many jewelry alloys within seconds. KLEVE, GERMANY- SPECTRO Analytical Instruments, a unit of AMETEK, Inc., has equipped the SPECTRO xSORT handheld XRF spectrometer with a new application package for precious metal analysis.
