Advantages
The smallest OES
Metal Power’s MOSS redefines miniaturisation in the field of optical emission spectrometry. With its minimal footprint, it fits easily onto any workbench, transforming a corner of the workshop into a fully-fledged quality control centre. It makes no compromise on performance thanks to its optical system based on state-of-the-art CCD detectors. This technology enables the analysis of all critical elements (carbon, sulphur, phosphorus, etc.) with high precision.
Wide elemental coverage
The Moss is capable of analysing more than 40 elements, including 25 in steels.
The detection limits for carbon, sulphur and phosphorus are as low as 50 ppm, and 5 ppm for boron. This OES spectrometer is ideal for analysing cast iron, steel and aluminium.
Equipped with an advanced argon-saving system, the Moss offers over 2,000 burns per cylinder.
Simplified operation and versatility
The MOSS is capable of analysing samples with complex shapes or small dimensions, such as fine wires up to 3 mm in diameter or small samples measuring 4 to 13 mm, offering great versatility.
This benchtop OES spectrometer features a user-friendly interface and streamlined software. Even with basic training, operators can easily use Metal Power’s MOSS.
