提高红外分光光度计分辩率可从以下几个方面着手: 一、改善使用条件首先可以提高仪器的增益,但增益提高,噪音增大,增益调到不致影响观察吸峰为好。其次可减慢扫描速度,它常常收时间常数的增大相配合,有些仪器的光与源强度可以改变,当探测器接收能量弱时,增加光源强度可以提高分辨率。还有些仪器的狭缝大小可以改变,当探测器接收能量强时减小狭缝以减小光谱带宽;当探测器接收能量太弱时增大狭缝以增加能
Improve the resolution of infrared spectrophotometer from the following aspects: First, to improve the use of conditions First of all, you can increase the gain of the instrument, but the gain increases, the noise increases, the gain adjusted to not affect the peak absorption is better. Second, it can slow down the scanning speed. It often matches with the increase of time constant, and some instruments can change the light and source intensity. When the detector receives weak energy, increasing the intensity of light source can improve the resolution. Still others may have varying slit sizes that reduce the slit when the detector receives more energy to reduce the spectral bandwidth, increase the slit to increase when the detector receives too little energy
