分光光度计示值不稳定的原因较多,但分析起来大致为三类:光路、电路和样品室。本文系根据实际经验,依次列举国产分光光度计示值不稳定的主要来源和采取的措施。一、光路 1.当光源、反射镜、透射镜上沾有灰坐时,因温升和气流使附着的灰尘移动,医此到达光电转换器件的光能量有相应的变化, Spectrophotometer instability for many reasons, but the analysis is roughly three categories: light path, circuit and sample room. This article is based on practical experience, followed by a list of domestic spectrophotometer instability of the main source of indication and the measures taken. First, the optical path 1 when the light source, the mirror, the mirror is stained gray sit, due to temperature and airflow to move the attached dust, the medical light reaches the photoelectric conversion device has a corresponding change in light energy,
