Material emissions

Vehicle interior air quality
Emissions from vehicle trim components can adversely affect vehicle interior air quality (VIAQ), raising concerns for passenger health and safety. This has been reflected in the development of harmonised methods to quantitate releases of chemicals released from the materials used, and assess the overall quality of in-vehicle air. Thermal desorption and related sampling methods are stipulated in these methods, to aid understanding of both the volatile content and emission profiles of car trim, as well as for analysis of in-vehicle air.
Construction products
Increased awareness of the potential health risks associated with poor indoor air quality has led to increasing calls for the regulation and labelling of construction materials used indoors. These regulations and labels (such as the European CPR and REACH, and a range of US-led initiatives) typically demand product testing in accordance with standard methods. Thermal desorption and related sampling techniques are increasingly being stipulated in these methods for their ability to rapidly produce meaningful emissions data.
Consumer goods
The rise of regulations relating to emissions from construction products is now starting to be mirrored for consumer products, with regulations already in place for dealing with bisphenol A (BPA) in childrens’ toys. Other projects concerned with emissions from fragranced products and a range of other commonly used household goods are currently in progress, and are expected to come into the spotlight over the coming years. Whatever the type of product, thermal desorption and related sampling techniques have a key role to play in providing rapid and meaningful emissions data for a wide range of key analytes.
Cleanroom contaminants
The rapid pace of innovation in electrical goods demands ever-greater quality of their components, where performance can be adversely affected even by very low concentrations of impurities. In the cleanroom environments where these items are manufactured, attention must therefore be paid to avoiding the presence of airborne molecular contaminants. To meet this demand, a range of techniques for monitoring cleanroom air and the materials used in cleanroom construction are available, with methods based on thermal desorption particularly valued for their ability to detect trace-level compounds.
Formaldehyde monitoring
Formaldehyde is one of the most abundant toxic pollutants in indoor air, being used worldwide in the manufacture of building materials and household goods. Regulations are now in place that set limits for formaldehyde release from furnishings and building materials. Although thermal desorption cannot be used for monitoring formaldehyde because of its reactivity, Markes’ Micro-Chamber/Thermal Extractor can be employed in conjunction with DNPH cartridges or on-line monitors for convenient formaldehyde detection.
