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:

  • Analog scan, scan rates > 0.2 s/u (*)

  • Scan Bargraph, scan Rates > 20 ms/u (*)

  • Multi Ion Detection (MID) up to 64 selectable mass numbers, scan rates > 10 ms/u (*)

  • Characteristic temperatures (Onset, Peak and End)

  • Peak areas for quantitative evaluation and calibration

  • Spectra subtraction
