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.
