Evolved Gas Analysis of Iron Powder using a TG/DTA System with a High-resolution Multi-turn Mass Spectrometer Thermogravimetry/differential thermal analysis (TG/DTA) systems are often used to analyze the thermal behavior of metal materials. These systems measure changes in sample weight as they relate to programmed oven temperatures. It is generally known that during the measurement process, as the weight decreases, gases are evolved.

Direct Analysis of a Methanol Flame by using a Compact High-Resolution Multi-Turn Mass Spectrometer The InfiTOF™ is a compact high resolution time-of-flight mass spectrometer (TOF-MS) that has a unique multi-turn ion optics system capable of providing a variable-length ion-flight path (up to 200m) in a very compact analyzer (20cm x 20cm). As a result of this, the InfiTOF allows the user to choose a resolving power based on path length in order to separate similar mass gas components like carbon monoxide and nitrogen as CO+ (m/z 27.9949) and N2+ (m/z 28.0062).

Analysis of Reaction Gases in a PECVD Chamber: Reaction Analysis using a High-Resolution Mass Spectrometer Plasma-enhanced chemical vapor deposition (PECVD) is an evaporation technique that forms various thin films on a substrate using a material gas in a low-vacuum chamber. PECVD, which decomposes the material gas via plasma, is widely used to develop silicon, silicon oxide, and silicon nitride films in semiconductor device fabrication.

Real-Time Monitoring for Gas Phase H/D Exchange Reaction of H2O and D2O by Using a Compact High-Resolution Multi-Turn Mass Spectrometer The InfiTOF™ is a compact high resolution time-of-flight mass spectrometer (TOF-MS) that has a unique multi-turn ion optics system capable of providing a variable-length ion-flight path (up to 200m) in a very compact analyzer (20cm x 20cm). The InfiTOF is able to: Detect small elements/molecules such as H+ and H2+. Allow resolving power selection based on the chosen path length for the ions. Achieve mass separation of gas components like carbon monoxide and nitrogen as CO+ (m/z 27.9949) and N2+ (m/z 28.0062). Record long-term measurements with high m/z stability (Fluctuation < 100ppm/hour), high sensitivity and high mass accuracy. The InfiTOF enables “In-situ” high-resolution monitoring of real-time gas phase reactions. In this work, we show the real-time monitoring of a simple H/D exchange reaction of light water (H2O) and heavy water (D2O).

Direct analysis of a butane combustion flame by using a high -resolution multi-turn mass spectrometer Butane is known to be the main component of liquefied petroleum gas and is widely used as a fuel. The elementary mechanistic reactions that occur during premixed butane/air combustion have been investigated through computer simulations. However, there are relatively few experimental mass spectrometric studies that supplement these computer simulations due to the technical challenges of combustion product sampling from within the premixed butane/air flame. The JMS-MT3010HRGA is a compact high-resolution multi-turn mass spectrometer the can be used to measure combustion products. In this report, we identified combustion products in the premixed butane/air flame by using the JMS-MT3010HRGA. March 5, 2020 Application Note, InfiTOF™, Mass Spectrometry (MS) 0 Comment Read More >>
Analysis of a Gas Mixture Containing Ammonia and Methane by Using a Compact High-Resolution Multi-Turn Mass Spectrometer Analysis of a chemical ionization reagent gas consisting of a 5% mixture of ammonia in methane is demonstrated by using the JEOL InfiTOF™ compact high-resolution mass spectrometer.
