英國阿朗 ARUN Technology
英國阿朗（ARUN）臺式/便攜式金屬分析光譜儀
阿朗光譜分析儀有兩大系列，現場用的便攜式金屬分析儀（M3000/1650) 和實驗室或爐前分析用的臺式直讀光譜儀（M2550/2560）。幾年來中國已有近兩百個用戶。
M2550、M2560具有實驗室級的分析精度，分析范圍涵蓋有色金屬和黑色金屬領域全部。事實上，除了體積上的區別，阿朗METALSCAN 2500系列臺式光譜儀與傳統光譜儀在分析范圍方面幾乎是一樣的。M2550、M2560在添加基體或校準曲線時無需增加任何硬件成本，這是傳統光譜儀無法做到的。
M1650、M3000是創新的便攜式金屬分析儀，用于現場對各種金屬進行快速近似定量、定量分析及合金牌號鑒別。

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 few moving parts and no potentially dangerous radioactive isotopes.

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 PolySpek with multi-optics and 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 'A' 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.

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.
