摘要
介绍了Lab-X3500定硫分析仪的测定原理、分析流程和主要特点。此仪器采用X射线荧光法测定石油产品中的硫,通过探测仪和微型计算机将特征X射线的光子能量转化为脉冲形式的电信号测出硫含量。与国标方法进行线性回归校正后,仪器测量值与国标法测定值有较好的一致性,且分析速度快,有利于石油产品中硫的时时监控。
The measurement principles and analytiocal flow path and characterisitics of Lab-X3500 are described. The instrument determines sulfur in the petroleum production by X-Ray fulorescence spectrometry. Photon of the special X-ray change into pulsed electric signal to determine sulfur by detector and microcomputer.The measured sulfur values are in good agreement with value obtained by standard method after calibration by liner regression.The method is fast,so it can be applied to online automatic instrument.
