Applied photophysics stopped-flow upgrade

应用光物理SX.18MV止流荧光/吸收光谱仪最初于1995年购买，并于2003年升级，配备了新的样品处理单元（流动池和驱动闸板）和止流值/注射器组件。这台光谱仪一直是一个主力，对圭尔夫大学几个部门的许多研究人员的研究项目做出了重大贡献。然而，操作系统（OS）一直是北美用户的一个棘手问题，因为仪器操作系统是基于英国的Acorn平台。本提案是一份资金申请，用于将仪器从其Acorn操作系统升级为新的计算机接口、仪器控制软件和操作系统（Windows XP）。仪器的硬件和机械仍然很好，但是现在的操作系统已经过时，使得数据采集缓慢而繁琐。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的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。

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.
