Detailed description

This test cell has been designed for in-situ Raman spectroscopy combined with electrochemical methods. The test cell is airtight and can be used to study air- and moisture-sensitive samples.

By default, the TSC Raman is provided with a working electrode contact made of stainless steel. The electrode material needs to be prepared as round-shaped specimen with an outer-diameter of max. 12.0 mm. The electrode material is placed on top of the working electrode contact. When assembling the test cell, the sample is pressed against the optical window. In consequence, a very thin liquid film is formed on the working electrode, enabling the study of the solid-liquid interface. When a larger distance between the quartz glass window and the sample surface is required, a ring-shaped glass-fibre separator can be put between working electrode and quartz glass window.

A gold-plated stainless steel ring electrode serves as counter electrode. An electrolyte amount of 2.0 ml is required. Lateral inlets enable the positioning of metal-wire based pseudo reference electrodes. In addition, these inlets also can be used for initial filling of the cell by means of the capillary-based filling set.
