UV-vis spectrometer replacement

点击翻译按钮获取中文摘要

Chemical reactions can occur on very fast time scales that require specialized equipment to follow. The laser/fluorescence facility at UVic is set-up to measure reactions that occur from nanoseconds to many seconds. The UV-Vis spectrometer is essential as support equipment for laser flash photolysis, fluorescence, single-photon counting and stopped flow experiments. The absorbances of solutions have to be known exactly before any of the experiments listed above are performed. In addition, when high powered excitation sources, such as lasers, are used it is a requirement to check frequently during the experiment for the potential decomposition of the sample. For this reason, the Cary 1 UV-Vis spectrometer is routinely used during all experiments. The Cary 1 is now 17 years old and has been declared obsolete by the manufacturer. This proposal urgently requests funds for a replacement of the Cary 1. The permanent break-down of the Cary 1 would negatively affect the work of 8 research groups that use the laser/fluorescence facility.
