KLEVE, Germany, July 5, 2011 — Spectro Analytical Instruments GmbH, a unit of Ametek Materials Analysis Div., has unveiled an updated version of its Spectrolab metal analyzer that incorporates a number of improvements and achieves better detection limits than its predecessor vis-à-vis trace analysis of pure copper and aluminum.

Its hybrid optic processes light directly from the spark stand with photomultipliers and CCD detectors simultaneously. The instrument offers the advantages of photomultiplier detectors relative to single spark evaluation and time-resolved spectroscopy along with the flexible line selection and ability to combine analytical and reference lines from CCD detectors. It delivers low detection limits with stability and repeatability of measurement results,

Optimized excitation parameters and an innovative readout system enable permanent enhancements for lead analysis, with a focus on battery technology and analysis of precious metals. The device can be used for automotive and aerospace materials testing, and it analyzes aluminum, magnesium and titanium alloys with a single hardware configuration. The spectrum from 120 to 780 nm is now available to users.

The instrument provides new options for incoming and outgoing controls and for analysis of unknown metallic materials. With its optimized optical resolution and a focal width of 750 nm in both optical segments, it produces good analytical results for trace analysis of pure metals and the examination of all material combinations and alloys.

In redesigning the metal analyzer, the company emphasized ease of operation and reduced operating costs. It placed components that could require maintenance in easily accessible locations. An extended diagnosis and log file system assists users in monitoring the instrument’s status and in performing accurate troubleshooting, helping to lengthen maintenance intervals and shorten repair times.

As a high-end optical emission spectrometer, it addresses the needs of metal producers and processing companies as well as those of the automotive and aviation industries. It is well suited for use in quality management applications and for materials analysis for incoming and outgoing controls, and is a cost-effective solution for businesses that work with many different metals and that previously had to maintain multiple analyzers. It can be configured to analyze all 10 common base materials, eliminating the need for a second instrument.
