Evolved Gas Analyzer

MAX300-EGA Evolved Gas Analyzer

The MAX300-EGA quadrupole mass spectrometer is the newest Evolved Gas Analyzer within Extrel’s high performance MAX300 family. 

  • Designed for coupling with instrumentation in thermal analysis, pharmaceutical, materials science, and organic chemistry laboratories, the MAX300-EGA features Extrel’s industry-leading 19 mm quadrupole mass filter.
  • High sensitivity, resolution, and flexibility make the MAX300-EGA ideal for the characterization and quantitation of your off-gas.
  • Equipped with a 2 m heated transfer line, an extensive compound library, and the ability to import a variety of external signals, the MAX300-EGA is optimized for interfacing with thermal analyzers and microreactors.
  • The chemically inert capillary keeps the sample hot and under vacuum all the way from the furnace to the ionizer to prevent condensation and chemical interaction during transit.
  • Data synchronization couldn’t be easier; the Questor® 5 software comes standard with the ability to receive external signals, like the Start-of-Heating signal from a TGA. Trend and manipulate data within Questor® 5, or simply export it for use on a different platform.
