Easy-VOC

In this Applications Guide, Markes International describe how thermal desorption (TD) can be used for key applications in the field of food and drink VOC profiling – covering everything from comparing brands of cheese, to improving the shelf-life of ready-to-eat fresh-cut fruit.

This application note describes the use of an easy-to-use grabsampler for the rapid collection of volatile compounds in the headspace surrounding packaged meat. Analytes are collected directly onto sorbent tubes for analysis by thermal desorption (TD)–GC–MS. This approach offers particular advantages in terms of sensitivity enhancement and water management.

This is a comprehensive guide to monitoring chemicals in the environment and the workplace using thermal desorption. It describes how thermal desorption can be used in air and water monitoring applications including detection of ‘air toxics’, mapping of environmental pollutants and assessing underground contamination. In each case, the guide directs you towards relevant application notes which describe the methods mentioned in detail. The guide also describes relevant analytical and sampling techniques and outlines the advantages of using thermal desorption for environmental monitoring.

This is a comprehensive guide to assessing the odor profiles of products and materials using thermal desorption. It details the many different products that can be profiled using thermal desorption such as tobacco, shampoo, and air fresheners and directs you to the relevant application notes which detail the methods used. The guide also describes relevant analytical and sampling techniques and outlines the advantages of using thermal desorption for fragrance and odor profiling.

This is a comprehensive guide to using thermal desorption in the vehicle-manufacturing industry. The guide describes how thermal desorption can be applied to various applications in the industry including vehicle interior air quality monitoring, analysis of polycyclic aromatics hydrocarbons (PAHs) and detecting volatile carbonyl compounds, and directs you towards relevant application notes which describe the methods in detail. The guide also describes relevant analytical and sampling techniques and outlines the advantages of using thermal desorption in automotive studies.

This is a comprehensive guide to how thermal desorption is being applied to advance research into human health, atmospheric chemistry and chemical ecology. The guide details how thermal desorption is used diverse branches of biological research such as disease diagnosis, monitoring of marine halocarbons and interspecies interactions and in each case, directs you towards relevant experimental data from published research.

This is a comprehensive guide to the use of thermal desorption to assess chemical emissions from construction materials and consumer products.
