Preparing and introducing standards using thermal desorption tubes
Application Note 007
Calibration and quality control are integral to any quantitative analytical method, and it is important that the loading and analysis of calibration standards replicates, as closely as possible, those of the samples themselves.
For this reason, tube-based thermal desorption–gas chromatography (TD–GC) systems should be calibrated by loading standards onto sample tubes and desorbing them through the complete two-stage TD process.
There are two types of standards for tube-based TD: calibration standards and internal standards.
This application note explores the use of calibration standards and internal standards.
