Microwave Assisted Wet Digestion in Closed Vessels with Simultaneous Control of Pressure and Temperature in All Vessels

Project: Research project

Project Details


A novel system for micowave assisted wet digestion in closed vessels is/will be developed. During sample decomposition, the pressure and temperature are measured in each vessel. The pressure and temperature data are transferred from the rotor by means orf infrared ligth to the control unit. this means that no pneumatic or electronic connections to the vessels need to be established, giving very easy handling. The temperature history of each vessel is recorded, so the progress of each sample digestion may be reconstructed later on. Thus the requirements for quality control in sample digestion are available for the first time. For sample digestion at 75 bar and up to 280°C quartz vessels with 50 ml volume are used. Depending on the matrix the maximum sample loading capacity is 1.2 g. TFM-vessels with 100 ml volume work at 30 bar up to 240°C.
