Arc-spark Optical Emission Spectrometers (OES) are critical quality tools for all metal industries – offering highly accurate and precise analysis of a plethora of elements within just seconds. Typically, these are key elements of every metal analysis laboratory. But there are situations when an OES is needed, but a Laboratory is infeasible! Examples of such applications include the need for rapid sorting of scrap, grade identification and sorting of materials in a yard – also called Positive Material Identification (PMI), quick testing of materials at the in-gates of plants, validation of large products that one can’t take a sample from or the validation joints on large vessels (ships, for example) etc. Such applications demand metal analysis and therefore require an Optical Emission Spectrometer but need the spectrometer to be capable of moving to the item that needs testing rather than the other way around. This creates the need for portable or mobile spectrometers, and this is where mobile OES (also sometimes referred to as Portable OES) come in. As one of the world’s leading spectrometer manufacturers, Metal Power offers the best and most optimized portable/mobile OES models in the industry!
Mobile OES take the myriad advantages of arc/spark OES and remove the constraints of needing a Laboratory environment and carefully prepared sample. The best mobile OES – like Metal Power’s Metavision-MX and Metavision-MX+ come with self-contained trolleys that house not just the optics and plasma generation sources, but also with in-built computers and touchscreens, and are equipped with wheels and suspensions designed to enable the unit to be wheeled around over extended distances in rugged conditions like those on a foundry or forge-shop or in scrapyards, shipyards etc. Extremely compact and completely self-contained, these OES can also just be loaded into small vehicles and driven to places where testing is needed (e.g. scrapyards visited for purchasing / sales). This enables users to move the instrument to the point where testing is needed – making the OES both mobile / portable and transportable. For sparking, the mobile OES is equipped with handheld probes at the end of 4m (or longer) conduits. Multiple probe options are provided enabling users to select the mode of testing needed. Users can also select from a variety of sample adaptors, enabling analysis of different types of shapes, including curved surfaces (for inspection of items such as wire rods), angles (for inspection of weld joints, for example) etc. What makes mobile OES far preferable to any other “portable” spectrometer or other handheld models is the ability to test for UV elements including C, S, P, B, As and N. Mobile OES can test for C in all three modes (arc, spark and UV) while the UV probes address the needs for testing all these elements to low levels (down to 20 ppm and lower). This makes mobile OES far preferable to other portable or mobile options – particularly XRF – as these do not analyse UV elements at all.
