Markes International has launched a Humidifier Accessory, which extends the capability of their Micro-Chamber/Thermal Extractor by supplying it with humidified air or gas.
The availability of a regulated supply of humidified air or gas means that chemical emission profiles can now be obtained under conditions that are a better match for real-life scenarios. This is important because the rate of release of some compounds is significantly affected by humidity.
The Micro-Chamber/Thermal Extractor, which operates on the principle of dynamic headspace sampling, is a compact stand-alone unit that is widely employed for the screening of chemical emissions from products and materials – especially those that are used in buildings and vehicles.
