Temperature and power consumption for tungsten coil in the drying process of liquid samples

摘要

This paper presents experimental data obtained with a tungsten coil during the drying process of a sample solution used in electrothermal evaporation. The aim of these experiments consists in analyzing the tungsten coil temperature variation correlated with the sample volume, respectively the electrical power applied. An equation for the drying process was obtained based on the collected information. The equation can be embedded in an intelligent power supply, optimizing thus the drying process for different operating modes. The data obtained in this work follows up information to the publications in the spectrometric field of analysis methods using tungsten coil in electrothermal evaporation process.
