The Applied Photophysics SX.18MV stopped-flow fluorescence/absorption spectrometer was originally purchased in 1995 and it was upgraded in 2003 with a new sample handling unit (flow cell and drive rams) and stopping value/syringe assembly.  This spectrometer has been a workhorse and has contributed significantly to the research programs of a number of investigators in several departments at the University of Guelph. However, the operating system (OS) has always been a thorny issue with North American users since the instrument OS is the United Kingdom-based Acorn platform. This proposal is a request for funds to upgrade the instrument from its Acorn OS with a new computer interface, instrument control software, and operating system (Windows XP).  The instrument hardware and mechanics are still in wonderful shape, but the present OS is antiquated and makes data acquisition slow and tedious.  Furthermore, file sharing and data analysis require extra conversion steps, especially when using external fitting and data plotting/graphing programs.  This last upgrade will convert our Applied Photophysics instrument to the current standard of the new 2007 SX-20MV spectrometers and should extend the practical lifetime of this instrument to several more years.

Applied Photophysicals SX.18MV 停流荧光/吸收光谱仪最初于 1995 年购买，并于 2003 年进行了升级，配备了新的样品处理单元（流动池和驱动柱塞）和停止值/注射器组件。  该光谱仪一直是圭尔夫大学多个系的许多研究人员的主力，并为他们的研究项目做出了重大贡献。然而，操作系统（OS）一直是北美用户的棘手问题，因为仪器操作系统是英国的Acorn平台。该提案是一项资金请求，用于将仪器从 Acorn OS 升级为新的计算机界面、仪器控制软件和操作系统 (Windows XP)。  仪器硬件和机械结构仍然完好，但现有的操作系​​统已经过时，使得数据采集缓慢而乏味。  此外，文件共享和数据分析需要额外的转换步骤，特别是在使用外部拟合和数据绘图/绘图程序时。  最后一次升级将把我们的应用光物理仪器转换为新型 2007 SX-20MV 光谱仪的当前标准，并将该仪器的实际使用寿命延长几年。
