Since the 1980’s when it launched the world’s first commercial portable metals analyser incorporating a diode array, ARUN Technology has led the world in the fast growing market for portable and desktop CCD-array analysis systems for metal or metallurgical applications.
The Charge Coupled Device (CCD) technology, which is similar to that used in digital cameras, phones and video recorders, enables a single, small, yet robust instrument to measure the whole spectrum necessary for the analysis of all the common metal bases. In fact the most appropriate analytical or spectral ‘lines’ can be chosen by software rather than hardware such that MetalScan spectrometers are not limited in the number of elements that can be analysed. For example a typical conventional spectrometer incorporating Photo Multiplier Tube (PMT) detectors might have about 30 analytical channels fixed by expensive hardware, while a CCD based unit would have access to over 1000 channels, all selectable by software. The CCD provides an electronic slit plate where electronics can be used to search for line peaks and counteract any thermal or mechanical shifts, which are often the source of problems with conventional units.
MetalScan spectrometers incorporate mechanical. optical and electronic parts but no moving parts nor any potentially dangerous radioactive isotopes or X ray tubes.
In the 1990’s ARUN Technology introduced the MetalScan M1650 the world’s top-selling portable emission spectrometer followed shortly by the MetalScan M2000 the world’s first desk-top OE spectrometer, combining low cost CCD array technology with a high precision spark source and laboratory analytical software.
Over the last twenty years, the range of products offered by ARUN Technology and the performance levels available have both increased. The current M2500 series can offer flushed optics for the far u/v spectrum, vital for ferrous analysis of phosphorous sulphur and carbon, non-flushed optics for non-ferrous applications, LCD touch screens and internal industrial processors or external, standard personal computers.
A new range of portable spectrometers the M3000 series has also been introduced offering ac spark, dc arc, or both types of excitation. The dc arc mode offers rapid grade identification while the spark mode provides low-level carbon determination, typically separating stainless L non-L grades. Trolleys, battery packs and other accessories are also available.
More recently the higher performance PolySpek series of desktop units has been introduced incorporating multiple optics, multiple CCD arrays and updated analytical software.
In early 2006 ARUN Technology returned to private ownership as part of a management buyout under a new company MetalScan Limited. An independent company based in the UK, ARUN Technology can now offer the levels of cooperation and flexibility- technical as well as commercial - demanded by modern industry.
