为克服或减少稳定性造成的误判,减少用户经济损失,提高分光光度计的使用效能,有必要对仪器检测样品稳定性欠缺进行主要因素分析,如图1所示。光源光学系统(单色器)拉杆稳压电源(检测用接收器)放大器样品室对数放大220V数控显示打印由图1可看出影响仪器稳定性的主要部分:电器电子电路、光学系统、机械系统和电网供电等。前三项是内在因素,最后一项是外在因素。
To overcome or reduce the misjudgment caused by stability, reduce user economic losses and improve the efficiency of the spectrophotometer, it is necessary to analyze the main factors of the instrument to detect the lack of stability, as shown in Figure 1. Light source optical system (monochromator) lever power supply (detection receiver) Amplifier sample chamber logarithmic amplification 220V CNC display print Figure 1 can be seen from the main parts of the stability of the instrument: electrical and electronic circuits, optical systems, machinery System and grid power supply. The first three are intrinsic and the last is external.
