线性是衡量可见分光光度计的重要技术指标之一.如果线性超出检定规程所规定的误差范围,则仪器不能用于定量分析。在操作方法符合要求、单色器出射的单色光能达到规定的指标和光源电压稳定的前提下,影响仪器线性的主要因素有两部分:接收部分和显示部分.这里以721型分光光度计为例,对其线性误差的调修方法作一介绍,供参考。
Linearity is one of the most important specifications for measuring visible spectrophotometers, and the instrument can not be used for quantitative analysis if the linearity exceeds the error range specified in the verification protocol. In the operation method to meet the requirements, the monochromatic light emitted monochromatic light to achieve the required indicators and the light source voltage stability under the premise of the main factors that affect the linear instrument has two parts: the receiving part and the display part here 721 spectrophotometer For example, the method of adjusting the linear error made an introduction for reference.
