Abstract

The interfacing of a commonly used spectrophotometer, the Hitachi U2000, through its RS-232C port to a IBM compatible computer is described. The hardware for data acquisation was designed by suitably modifying readily available materials, and the software was written using the C programming language. The various steps involved in these procedures are elucidated in detail. The efficacy of the procedure was tested experimentally by running the visible spectrum of a cyanine dye. The spectrum was plotted through a printer hooked to the computer. The spectrum was also plotted by transforming the abscissa to the wavenumber scale. This was carried out by using another module written in C. The efficiency of the whole set-up has been calculated using standard procedures.

采用rs - 232c型计算机的日立U-2000分光光度计自动光度计。
描述了一种常用的分光光度计,日立U2000,通过其RS-232C端口与IBM兼容计算机的接口。通过适当修改现有资料,设计了数据采集的硬件,并用C语言编写了软件。详细阐述了这些程序所涉及的各个步骤。通过运行菁染料的可见光谱,实验验证了该方法的有效性。光谱是通过连接在计算机上的打印机绘制的。通过将横坐标变换为波数尺度,绘制了光谱。这是通过使用另一个用c语言编写的模块来实现的。整个装置的效率已使用标准程序进行了计算。
