M. Wendler

Methods and equipment available

Methods:	Production of digestions for ICP spectrometry (proven digestion methods for low-alloy steels, alloyed steels, cast steel, cast iron, ferroalloys, Al, Cu, Mg, Pb, Sn, Zn alloys, sands) Production of digestions for classical analytical methods Titrimetry (e.g. for the determination of the content of e.g. to determine the contents of Femet, Fe(II), Fe(III), Feges and free lime in slags; Mn and Zn in alloys) Potentiometry (e.g. to determine the contents of Cr and V in alloys) Gravimetry (e.g. to determine the contents of Cr and V in alloys) Gravimetry (e.g. to determine the contents of Ni, Si and W in alloys) Determination of moisture and loss on ignition
Equipment:	Fume hoods, also for hydrofluoric acid and perchloric acid Analysing balances Laboratory hotplates and laboratory thermostats Magnetic stirrers, Ultrasonic devices Pipettes of different sizes pH meter, electrodes Membrane vacuum pump Isolation apparatus, laboratory centrifuge Drying oven
Typical applications:	The wet chemical methods are mainly used for sample preparation for ICP spectrometry. They are also used when samples are not suitable for other analytical methods due to their shape or mass
