Spark spectrometry (spark OES) works by igniting the plasma created by a high-energy spark discharged in an argon atmosphere between the sample and the counter-electrode. Measuring the light emitted during this process enables simultaneous quantitative analysis of all required chemical elements in less than 30 seconds. It is thus possible to detect all metals, semimetals as well as a number of non-metals like, for instance, carbon, phosphorous, sulphur, oxygen or nitrogen. With that, spark spectrometry constitutes an outstanding quality control process for the metal producing and processing industry. Spark spectrometry is suitable for production control and R&D purposes just as for incoming materials control and utilising secondary raw materials containing iron, nickel, cobalt, aluminium, copper, magnesium, zinc, lead, titanium…
“Automation” means designing an architecture around the spectrometer that will enable the analysis of production samples without any or with only minimal human intervention. While the customer is free to decide on the degree of automation, the concept should always take into consideration that the spectrometer itself forms the central device as it delivers the analysis results and with that is decisive for the success of the entire system.
OBLF’s ASM 1800 automatic sample grinding machine was specially developed for customers whose line of business demands automatic preparation of recurring sample types for spectrometer analysis.The fact that this sample-preparation machine was developed in-house by the same company that produces the spectrometer itself gives customers the certainty that the machine satisfies all requirements for spectrometer-compliant sample preparation despite its extremely favourable price-performance ratio.
