Increase your existing GC-MS usage and expand your business

Microchambers are compact, stand-alone test chamber units that allow rapid sampling of vapour-phase organic compounds from a product or material, complementing small-scale chamber testing by third-party laboratories.

Microchamber sampling is a type of dynamic headspace sampling and a powerful tool for increasing laboratory productivity. The technique is usually used in combination with sorbent tubes and off-line thermal desorption–GC–MS.

Microchambers are ideal for in-house industrial applications such as:

  • (S)VOC emission screening for routine quality control.
  • Evaluating prototype ‘low-emission’ materials/products during development.
  • Monitoring product uniformity/conformity between formal certification tests.
  • Comparing emissions from products within a range (e.g. different colours/patterns).
  • Checking the quality of raw materials. • Troubleshooting customer complaints.

Benefits 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.
