Marks Micro-Chamber

Expand your Lab capabilities: Emission screening of Construction materials & Consumer products

Fast and flexible sampling of chemical and odours released from materials and food

The Micro-Chamber/Thermal Extractor™ (µ-CTE™) is a versatile and compact unit with four small cylindrical chambers that enables the sampling of chemicals released from products or materials. Released volatile and semi-volatile organic compounds (VOCs and SVOCs) are collected onto sorbent tubes for analysis by TD–GC–MS.

Target application:

Applications range from emissions screening of construction materials, consumer products and car trim, to aroma or fragrance profiling
Designed for anyone needing to sample VOCs or SVOCs emitted from products and materials
Humidifier and permeation accessories extend capabilities of the instrument.

Advantages of microchamber sampling

No sample preparation needed – simply place the material in the chamber.
A constant flow of heated air or gas ensures rapid production of a representative VOC/SVOC profile.
Results can be correlated with longer-term reference methods.
Construction from inert-coated stainless steel ensures compatibility with reactive or thermally labile chemicals.
Accessories allow surface-only sampling or permeation testing.
No pump required – avoids set-up and calibration.

Benefits of the Micro-Chamber/Thermal Extractor

Fast and efficient – The µ-CTE avoids the need for time-consuming sample preparation, and sampling is complete within minutes rather than days.
Cost-effective – Using the µ-CTE saves time and money by minimising the need for third-party reference tests.
Wide analyte range – Released volatiles are captured onto sorbent tubes (for VOCs and SVOCs) or DNPH cartridges (for formaldehyde), and all surfaces are inert-coated for compatibility with reactive or thermally labile chemicals.
Predict the results of reference tests – Data from the µ-CTE has been shown to correlate with longer-term tests carried out using small chambers.
Method-compliant – The µ-CTE complies with international standard methods ISO 12219-3 (interior air of road vehicles) and ASTM D7706 (rapid screening of VOC emissions from products).
Sampling versatility – As well as sampling emissions from bulk samples, a range of accessories allows sampling of surfaces or permeation through materials, humidification of air/gas, chamber calibration, and easy cutting of foam samples.
