分光光度计是药检所进行检测工作的物质基础,也是检验过程中影响数据质量的重要因素之一。因此,对分光光度计的波长校正非常必要,可对整个检验过程进行质量控制,使以良好的技术状态为检验服务,并能有效地保证检测数据的准确、可靠。 1.波长校正的重要性 各类分光光度计,波长调节装置一般均为机械放大结构,其中又分为棱镜分光式和光栅分光式,虽然这两种分光方式不同,但波长调节装置都采用金属部件。由于金属热胀冷缩性质,因此,不可避免地将受 Spectrophotometer is the material basis for drug testing carried out by the inspection, but also one of the important factors affecting the quality of the data during the test. Therefore, it is very necessary to calibrate the wavelength of the spectrophotometer, which can control the quality of the whole inspection process, make the inspection service with good technical condition, and effectively ensure the accuracy and reliability of the inspection data. 1. The importance of wavelength correction Various types of spectrophotometer, wavelength adjustment devices are generally mechanical amplification structure, which is divided into prism and grating grating spectroscopy, although the two spectroscopic methods are different, but the wavelength adjustment devices are used metal part. Due to the nature of metal thermal expansion and contraction, therefore, will inevitably suffer
