Application of Pfeiffer Mass Spectrometer

Pfeiffer gas mass spectrometerIntroduction:


OmniStar/ThermoStarTop of the line gas analysis system, suitable for qualitative analysis, quantitative analysis, atmospheric sampling of various gases. The capillary tube can be heated and temperature controlled to ensure the smooth transfer of the sample gas to the mass spectrometer and avoid the influence of water vapor on analysis. High detection sensitivity and accuracy.

Mass spectrometerApplication Example 1 of Omnistar/ThermoStar: Combination of Differential Reactor and OmniStar





Differential reactor is a gas experimental system that customers can configure according to their own experimental needs, in conjunction with PFEIFFERmass spectrometerThe main purpose of using OmniStar is to analyze the content of nitrogen oxides and ammonia in experiments, in order to determine the amount of gas changes in the reaction.

Mass spectrometerApplication Example 2: BEL-CAT Adsorbent Instrument Combined with OmniStar

Catalyst analyzer BEL-CAT and PFEIFFERmass spectrometerOmniStar is used to measure the surface acidity of adsorbent materials. Adsorption experiments are conducted based on temperature changes and changes in NH3 TPD/TPR content. The ammonia content is determined by measuring the peak value of ammonia changes using mass spectrometry.

ThermoStar application in TA/TGA thermogravimetry analysis



Thermogravimetric analysis (TGA) is used to determine the decomposition temperature, decomposition rate, and thermal stability of materials.
When a substance is heated, it undergoes chemical reactions or decomposition, and its quality changes accordingly. By measuring the changes in the quality of a substance, the process of change can be studied. ThermoStar can connect capillaries through TGA interface and use synchronous software to analyze the complex gases emitted after combustion.

Thermogravimetric Analysis (TG or TGA) is a technique used to study the thermal stability and composition of materials by measuring the relationship between the mass and temperature changes of the sample under program controlled temperature. Thermogravimetric analysisMass spectrometry analysisThe method can study the changes in crystal properties, investigate the thermal stability, decomposition process, dissociation, oxidation-reduction, quantitative analysis of composition, moisture and volatile compounds, reaction kinetics and other properties of substances.
