光谱分析中空白与检出限的讨论

Discussion on Blank and the Detection Limit in Spectum Analysis

空白、检出限是分析化学中两个基本概念。本文拟从痕量分析的要求出发，以理论与实验数据结合的方式对几种空白及它们对检出限的影响进行了讨论。

Blank and the detection limit are important parameters in spectrometry. Based on trace analysis,three kinds of blanks and the relation between blanks and the detection limit are discussed with experiment results and in theories.
