日本岛津ICPQ—100型电感耦合等离子体光量计具有自动校正共存元素干扰的功能。 共存元素(即干扰元素)干扰是指待测元素的谱线强度受相邻别的元素谱线和光谱背景的影响,导致待测谱线测得数值偏高或偏低,引起分析误差。对于这种干扰的影响必须校正。利用此仪器工作,可在测定过程中一次同时校正多达五个共存元素的干扰。 一、基本原理 本仪器的校正原理是基于把造成干扰的谱线强度相背景强度,由计算机转换成含量
Japan Shimadzu ICPQ-100 inductively coupled plasma spectrometer with automatic correction of coexisting element interference. The interference of coexisting elements (that is, interfering elements) means that the intensity of the spectral line of the element to be measured is affected by the spectral lines and the spectrums of other adjacent elements, causing the measured value of the measured line to be higher or lower, causing analysis error. The effect on this interference must be corrected. With this instrument, interferences of up to five co-existing elements can be simultaneously corrected in one measurement at a time. First, the basic principles The instrument calibration principle is based on the background of the intensity of the interference caused by the spectral intensity, converted by computer to content
