To activate the catalyst temperatures up to 300ºC can be applied. To study the Raman spectra, the temperature range is restricted to Room Temp ®200ºC. Coupling between the CAT cell is maintained using industry standard 1/16" capillary stainless steel tubing. Activated catalysts are frequently coloured and hence absorb the incident laser radiation when studying the Raman spectra. It is well established that this absorption can be minimised by moving the sample beneath the laser beam continuously. The Ventacon CAT cell gently moves up and down whilst spectra are recorded hence the laser beam tracks across the catalyst surface. The Ventacon CAT cell system must be powered by the Ventacon D Series Universal Power supply. These supplies provide energy for the oven and power and control the vertical translation system. All Ventacon cells operate within the sample chamber with the lid closed. See Safe Operation page for details of methods of communication between the sample area and the laboratory.
