Micro-Chamber / Thermal Extractor

The MARKES Microchamber is a practical tool for TD-GC-MS sample preparation. Four stainless steel outgassing chambers with fittings for TENAX tubes can be used in parallel to investigate the outgassing characteristics of materials (in addition with GC-MS-Analysis). This can be done applying purge gases and temperature profiles.

The chamber can be used to check surface or bulk emission profiles and to assess a wide range of samples from raw materials to finished products.


  • Raw materials like adhesives, glues, pottings, plastics
  • PCBs, ICs
  • Electronic components
