RG—1型单波长冷原子吸收热释测汞仪

RG-1 Monowavelength Cold-Vapor Atomic Absorption Thermal Release Mercury Analyzer

摘要: 介绍了采用“化学选择表面吸附”方法在气路中使用和ＮａＯＨ及Ｎａ２Ｏ２排除固样品热解产生的干扰气体的ＲＧ－１型单波长冷原子收测汞仪，仪器抗干扰能力≥３Ａ，允许直接热解纯硫２０ｍｇ及可能热解释放大量干扰气体的单矿物５０ｍｇ。主要技术眼过了双波长的塞曼原理测汞仪。

Abstract: A monowavelength coldvapor atomic absorption thermal release mercury analyzer is developed. NaOH and Na\-2O\-2 are used in the gas route to remove the interfering gases produced from the solid samples during thermal release step. The main technica
