Evolved Gas Analysis - QMS (EGA)

The QMS - quadrupole mass spectrometer coupling device is a state of the art mass spectrometer with a heated inlet system. The QMS is used for the analysis of volatile decompositions. All Linseis instrumentsare especially designed to guarantee a user friendly operation of both the Thermal Analyzer and the Mass Spectrometer. A integrated Software solution is certainly available.

Example System: Coupling Thermo Balance TG/STA + Quadrupol Mass-spec(QMS):

Both manufacturers Linseis and Pfeiffer are some of the leading companies in their specialized fields. This cooperation guarantees outstanding performance for the combined system.

• Transfer line is temperature controlled up to a maximum of 250°C.
• Fast response time through short transfer line.
• MS detector with very high sensitivity and with different mass numbers available.

The following applications can be measured:

• Outgasing components of burned material (paints etc.)
• Determination of blenders and additives.
• Absorption and Desorption processes.
• Analysis of rubbers and plastics.

Features

• Linseis Research balance (different models) with TG or simultaneous TG/DSC or TG/DTA measurement.
• Simultaneous balance with (0.1/0.5/1µg) resolution and 25gram max. sample weight.
• Specific heat measurements (Cp) possible.
• Pfeiffer/Balzers mass spectrometer model Thermostar (0 - 100 amu, 0 - 200 amu, 0 - 300 amu)
• Highest precision Quattropol-MS from world leader in MS Technology.
• MS with very compact dimensions.
• Very easily exchangeable quartz capillary.
• Three separate heating zones, at capillary, at TG protection tube and at MS vacuum inlet.
• Carrier gas with wide range of flow rates.
• Especially developed Al2O3 "sniffer-nose", to extract the out gases.
• Combined results of TG and MS available in one evaluation sheet.
• Complete vacuum tight system.

Pulse-Analysis

The Pulse-Analysis injects a exactly predetermined amount of liquid or gas into the Thermobalance (TGA) or Simultaneous Thermal Analyzer (STA). This enhances the measurement possibilities significantly: the MS or FTIR can now be calibrated. Out gassings can be quantified precisely with this method.
