TT24-7

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 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. It describes how the standard methods developed to assess emissions from construction materials and consumer products are compatible with thermal desorption. The guide goes onto details how thermal desorption can be applied to various techniques in assessing consumer environmental health, from near-real-time-air monitoring to assessing formaldehyde emissions, and directs you towards relevant application notes which describe the methods in detail.

This application note looks at the near-real-time analysis of the compounds released from a plug-in air freshener, using the TT24-7™ thermal desorber combined with GC–MS. The fragrance diffused into the room, and the air was sampled continuously to monitor the compounds released as their concentrations changed over time.

A new transportable thermal desorption system (TT24-7) has been developed by Markes International Ltd, which enables continuous online sampling and pre-concentration of airborne chemical warfare agents. The enriched vapor sample is subsequently analyzed using GC, GC/MS, or direct MS technology. This application note describes an evaluation of TT24-7 performance for trace level agents with both off-line and near real-time operation discussed.

This application note shows how the TT24-7™ Series 2 thermal desorber can be used for the continuous on-line detection of hazardous air pollutants, and how the time profiles and concentration data obtained can be of value for source apportionment.

This application note describes an evaluation of TT24-7 performance for trace level agents, such as HD and free (underivitised) VX. Both off-line and near real-time operation is discussed. Linear FPD calibration curves ranging from 15 ng to 10 pg for VX and from 2 ng to 0.2 ng for HD are presented.

In this application note from Markes, read about the new TT24-7 Series 2 for round-the-clock monitoring of volatile organic compounds in air or gas streams. Interfacing with any GC, it allows continuous analysis with high sensitivity and no blind spots. It is an ideal choice for advanced environmental research, monitoring pollution levels, controlling air/gas purity, and continuous odor or fragrance profiling.
