一次性综合检测钢铁中O、N、H三种元素含量方法的检出限分析与研究

Discussion on the Detection Limit of O,N and H Elements in Iron and Steel in One-time Comprehensive Test

检出限是氧氮氢分析仪重要的技术指标,是灵敏度和稳定性的综合指标,它反映了在检测中的总噪声电平大小,也反应了仪器设备的性能和方法的科学性、可行性。本文对首次提出的一次性综合检测钢铁中O、N、H三种元素含量的惰性气体熔融测定方法检出限进行了实验和分析。

Detection limit is an important technical index of oxygen,nitrogen and hydrogen analyzer,as well as a comprehensive index of sensitivity and stability.It reflects the total noise level in test and the scientific and feasible performance and method of equipment.This paper tests and analyzes the detection limit of the inert gas melting method for the first time in the comprehensive test of O,N and H elements in steel.
