Applied Photophysics Stopped-Flow Upgrade

应用光物理学SX-18 MV停流荧光/吸收光谱仪最初是在1995年购买的，2003年和2008年进行了升级，配备了新的样品处理装置、驱动注射器和操作系统。16年多来，该系统一直是一种主力系统，为圭尔夫大学几个系的许多研究人员的NSERC研究计划做出了重大贡献。这项提议要求在三个主要领域对仪器进行升级：(1)硬件/软件升级到Win7操作系统，(2)增加光电二极管阵列探测器系统，用于快速动力学光谱采集，以及(3)增加偏振硬件/软件，用于时间分辨荧光偏振实验。这最后一组升级将把我们的应用光物理仪器转换为新的2011 SX-20 MV光谱仪的当前标准，并将该仪器的实际使用寿命延长到几年。

The Applied Photophysics SX-18MV stopped-flow fluorescence/absorption spectrometer was originally purchased in 1995 and was upgraded in 2003 and 2008 with a new sample-handling unit, drive syringes, and operating system. This system has been a workhorse for more than 16 years and has contributed significantly to the NSERC research programs of numerous investigators in several departments at the University of Guelph. This proposal is a request for funds to upgrade the instrument in three major areas: (1) Hardware/software upgrade to Win7 operating system, (2) addition of a photodiode array detector system for rapid kinetic spectra acquisition, and (3) addition of polarization hardware/software for time-resolved fluorescence polarization experiments. This last set of upgrades will convert our Applied Photophysics instrument to the current standard of the new 2011 SX-20MV spectrometers and should extend the practical lifetime of this instrument to several more years.
