Liquid-cell_SENpro

A new heatable liquid cell was developed by SENTECH Instruments focusing on the requirements of the Institute for Chemistry and Biochemistry at Freie Universität (FU) Berlin. Experts from this institute visited SENTECH Instruments to get practical training at their own device before its delivery.

The liquid cell is characterized by three angles of incidence for optimal ellipsometric analysis, a small volume of about 26 ml and a heated sample plate. It has been developed for the special organic research of the Institute, where the reaction between enzymes and surface layers is investigated to detect enzyme-resistant films. A small pump is keeping the liquid in flow to prevent the enzymes from settling down on the layers unless because of chemical reactions. The temperature within the cell can be varied from room temperature up to 70 °C.Liquid-cell

At the FU Berlin, the modification of the layers is monitored by SENpro, SENTECH’s easy-to-use and cost-effective spectroscopic ellipsometer. The SENpro combines measurement speed with high accuracy of ellipsometric measurements applying SENTECH’s step scan analyzer measurement mode.
