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.
