UMTEC has various analytical devices and experimental setups to address issues in the fields of analytics as well as soil contamination, drinking water treatment, and wastewater treatment. Below, we present our most important devices.
The microwave digestion device is used in sample preparation for elemental analysis using ICP-OES to digest all types of solids or solid-containing liquids. Example application: Digestion of slags from waste incineration plants, roadside soils, or landfill leachate.
By centrifugation, the finest suspended solids can be separated from aqueous samples, and either the water and/or the solid fraction can be examined.
Application example: Centrifugation of nanoparticles from water samples or separation of pore water from soil samples.
This vibratory mill, developed for cryogenic grinding, is suitable for the comminution of sample quantities up to 20 ml. By integrating cooling of the grinding jar with liquid nitrogen, the sample is embrittled at -196°C. This allows materials such as soft plastics to be ground. Another advantage of the cooling is that volatile substances in the sample are preserved.
