  • Evaluation and improvement of the rapid multi-element determination of residual elements in steel for targeted production of steel quality by ICP-MS spectrometry


This project deals with the successful improvement of trace element determination by ICP-MS. Changing of physical and chemical properties of the sample solution by adding organic solvents and additionally using microflow injections of quartz and PFA increase the sensitivity up to a factor of 12 compared with aqueous sample solutions. A low amount of organic gas added to the plasma gas decreases the amount of interfering polyatomic ions especially shown on Mo- and W-determinations in steel.

Standard operational procedures (SOPs) according ISO conditions for trace element determinations by ICP-MS have been successfully developed for steel, dust and water. All information has been summarised necessarily to operate the instrument correctly, to prepare the sample in the right way, to clean the labware, to calibrate the measurement, and to calculate the results obtained. Well-defined operational settings were carefully investigated and are recommended corresponding to the general knowledge in the field and the special know-how to analyse steel, dust or water samples by ICP-MS using the types of instruments on the market (quadrupole and sector feed systems).

Rapid accurate and precise measurements of trace element amounts in steel have been performed by prior calibrating of the response curve of the instrument with all elements being determined. Hence, total analysis time can be reduced dramatically.
