光电直读光谱仪操作说明

photoelectric spectrometer operating instructions

光电直读光谱仪操作我们可以分为日常校准和工作曲线的建立。

The establishment of JB-750 photoelectric spectrometer Operation we can be divided into daily calibration and working curve:

一：日常校准Daily calibration

光电直读光谱仪操作可分为：磨样，狭缝扫描，标准化，控样校准和试样分析几个部分。

JB750type photoelectric directreading spectrometer operation can be divided into:sample grinding and slit scanning, standardization, control calibration samples and sample analysis several part

1：磨样

grinding

样品制备好对其进行后期的处理，就是在磨样机上进行磨制，被测样品激发的一面一定要平，使样品纹理清晰，才能保证样品与激发台之间贴合度， 这样才能保证气体冲洗室的密封性，使样品得到更好的激发。

Samples were prepared on the post processing, is in grinding machine for grinding,the sample to be measured excitation side must be flat, the sample texture clear, to ensure that the sample and excitation,and fit, so as to ensure gas washing chamber sealing,the samples were better excitation.

磨样机有以上两种可以选择，但是磨样机的转速必须要求在3600r/min，砂轮的粗细在36~60目之间，这样磨出的才符合光谱需求。
There are more than two kinds of grinding machine can choose, but the speed of the grinding machine must be required in the 3600r/min,the thickness of the grinding wheel in the P36~60 , so that the wear out of the spectral requirements.

2：狭缝扫描
Seam scanning
JB-750型光电直读光谱仪的光学系统都是按照仪器技术指标及光栅实际色散在生产过程中进行调整并紧固好的。出入射狭缝外其余部分不会相对位置的移动。但因温度及金属本身的变形会造成谱线相对出射狭缝位置的漂移。为了补偿这种缓慢的移动，在仪器的正常使用过程中，一般要求每天6~8个进行移动入社狭缝对出射狭缝的扫描，这样才能更好的进行样品分析，具体操作如下:
JB750 type photoelectric direct reading spectrometer optical system are in technical index of the instrument and the actual grating dinsersion in the production process adjustment and fastening,in addition to the entrance slit the rest not relative position of a mobile ,but due to the deformation of the temperature and the metal itself will cause spectrum relative exit Slit position drift ,in order to compensate for the slow movement,in the instrument during normal use ,the general requirements of every 6-8 for moving the entrance Slit of the exit Slit scanning ,so as to better sample analysis and specific operation as follows.
