751型和7520型紫外可见光分光光度计的光源调整,通常是在开启光源灯后进行,调整起来比较麻烦。这里介绍一种不需要接通仪器电源及光源的调整方法。1.氢灯的调整。首先将光源灯室外罩打开,把波长盘旋在580nm 处,狭缝开至2mm,光源选择柄放在被调整光源灯氢灯位置上,将滤光片滑板放在空档。打开仪器样品室的盖板,取出比色皿架,将特制辅助光源(见图1)放
751 and 7520 UV-visible light spectrophotometer light source adjustment, usually after turning on the light source lamp, adjust more trouble. Here is an introduction does not need to connect the instrument power and light source adjustment method. 1. Hydrogen lamp adjustment. First of all, the light source lamp housing cover is opened, the wavelength is circled at 580nm, the slit is opened to 2mm, the light source selection handle is placed on the hydrogen lamp position of the adjusted light source lamp, and the filter slide plate is put in the neutral position. Open the cover of the instrument sample chamber, remove the cuvette holder, and place the special auxiliary light source (see Figure 1)
