UV-vis spectrometer replacement

化学反应可以在非常快的时间尺度上发生，需要专门的设备来跟踪。维多利亚大学的激光/荧光设备用于测量从纳秒到数秒的反应。紫外可见光谱仪是激光闪光光解、荧光、单光子计数和停流实验必不可少的辅助设备。在进行上面列出的任何实验之前，必须确切地知道溶液的吸光度。此外，当使用高功率激发源（如激光）时，需要在实验过程中频繁检查样品的潜在分解。因此，在所有实验中都常规使用Cary - 1紫外-可见光谱仪。加里1现在已经17岁了，已经被制造商宣布淘汰。该提案迫切要求为更换Cary 1提供资金。凯里1号的永久性故障将对使用激光/荧光设备的8个研究小组的工作产生负面影响。

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.
