Evolved Gas Analysis (EGA)
STA 409 CD-QMS 403/5 SKIMMER Coupling System
Unique, Integrated Coupling System for Unlimited Gas Analysis
The SKIMMER coupling system with a quadrupole mass spectrometer (QMS) is worldwide the most sensitive system for thermoanalytical gas analysis. The coupling takes place directly in the furnace of the STA 409 CD, which is especially developed for the usage with the SKIMMER coupling.
QMS Features:
