Markes International has launched a humidifier accessory, which extends the capability of its Micro-Chamber/Thermal Extractor by supplying it with humidified air or gas.
The Humidifier accessory supplies the Micro-Chamber/Thermal Extractor with air or gas at up to 50% relative humidity.
Caroline Widdowson, material emissions applications specialist at Markes, said: “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 Humidifier Accessory will be particularly useful to Markes’ customers who have been using the Micro-Chamber/Thermal Extractor for routine quality control of product emission levels in manufacturing or R&D.
Widdowson added: “Standard reference tests, used for certifying product emission levels, use humidified air and may take up to a month. Many Marke’ customers use their Micro-Chamber as an alternative tool for quick in-house screening, and the new humidifier accessory will help them get results that correlate even more closely with those from reference tests.”
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.
