Abstract

A method for analyzing the atomic composition of organic compounds based on a filament RF discharge is proposed. The sample is prepared by heating it to 300°C in an argon atmosphere. The introduction of the sample into the discharge is carried out owing to the field electron emission of sample particles up to 300 µm in size. The optical emission spectra of particle atoms in the discharge are averaged. The method of internal standards for quantitative measurements is used. The sensitivity of the method for determining trace elements in human hair is at the ppm level.

关于使用灯丝RF放电分析有机化合物原子组成的可能性

摘要

提出了一种基于灯丝射频放电的有机化合物原子组成分析方法。通过在氩气氛中将其加热至300℃来制备样品。由于尺寸最大为300 µm的样品颗粒的场电子发射，将样品引入放电。对放电中的粒子原子的发光光谱求平均。使用用于定量测量的内标法。测定人发中微量元素的方法的灵敏度为ppm级。
