This guide introduces the features and applications of Markes International's thermal desorption (TD) instrumentation and associated sampling equipment. The guide is suitable for the measurement of VOCs and semi-volatiles in air and materials, including environmental monitoring, occupational exposure, and other applications.
This document serves as a practical applications guide for analytical thermal desorption (TD) technology. It highlights the capabilities of Markes International's TD instruments in measuring volatile organic compounds (VOCs) and semi-volatiles in air and materials without using organic solvents.
The guide covers various real-world application areas, including environmental monitoring, occupational health and safety, atmospheric research, and soil gas assessment. It details specific use cases such as monitoring chemical warfare agents, residual solvents in pharmaceuticals, and trace pollutants in urban air.
It is a sample introduction technique for GC and GC/MS that uses heat and a flow of inert gas to extract analytes from the sample media.
Relevant standard methods include EN ISO 16017, EN 14662 (parts 1 & 4), prEN 13649, ASTM D6196, US EPA TO-17 and NIOSH 2549.
