JEOL introduces the InfiTOF Spectrometer JMS-MT3010HRGA

August 2, 2016 By Arnold Kruize Product Introduction Compact MS, HR-MS, JEOL, MS, TOF, TOFMS 0

The InfiTOF  Spectrometer JMS-MT3010HRGA is a Time-of-Flight Mass Spectrometer using Multi-turn® and Perfect focusing® technologies, which achieves high mass-resolving power in a very compact package. This mass spectrometer is designed for real time monitoring of directly introduced gas. It is a high mass-resolution mass spectrometer with stability for real time gas monitoring and capable of elemental composition determination through accurate mass measurement.










High-Resolution Gas Monitoring

MS measurement results shown below are acquired by introducing the standard gases (10 ppm each) and then performing sequential measurement of 4 hours at high mass resolution conditions. High-resolution gas monitoring is enabled for all components over a long period of time with high stability.


High Mass Resolving Power

An innovative Multi-Turn technology makes the spectrometer compact while maintaining high mass resolving power. The maximum resolving power of 40,000 (FWHM) or higher is achieved even for a low-mass range, such as nitrogen molecule (28.0062 Da). With the conventional compact spectrometers, it was difficult to perform mass separation of gas components like carbon monoxide (27.9949) and nitrogen molecule (28.0062), or carbon dioxide (43.9898) and nitrous oxide (44.0011 Da). However, a new InfiTOF can easily separate these gas components and moreover, this revolutionized spectrometer calculates elemental composition through accurate mass measurement. 

Capable of Measuring Hydrogen Ions

JMS-MT3010HRGA is capable of measuring proton (1.0078 Da; a fragment ion of hydrogen molecule) as well as hydrogen molecule (2.0157 Da). Hydrogen is very difficult to measure with a time-of-flight mass spectrometer because of very low mass and fast flight velocity compared to other elements. The JMS-MT3010HRGA, however, achieves stable measurement of these species. This capability will contribute to research of various advanced materials, including electrolytic reactions and catalyst reactions.

  • JEOL is releasing new triple quadrupole mass spectrometer
    JEOL Ltd. (President Gon-emon Kurihara) announces the release of new Gas Chromatograph(GC) -  triple quadrupole mass spectrometer system, JMS-TQ4000GC on August, 2018. JMS-TQ4000GC is a GC-triple quadrupole mass spectrometer system with both capabilities of high throughput and high sensitivity based on the unique “Short collision cell technology”. Those capabilities can improve the productivity for routine analysis such as residual pesticides analysis in agricultural materials or monitoring of trace amount of chemicals regulated by tap water quality standard and environmental criteria in each region or country. It is expected that JMS-TQ4000GC would contribute to expand JEOL’s market share of not only GC-triple quadrupole mass spectrometer but also GC-single quadrupole mass spectrometer or GC –time-of-flight mass spectrometer. [Main Features] 1.   Short collision cell technology enables high speed data acquisition without crosstalk JMS-TQ4000GC can achieve the fastest SRM (Selected Reaction Monitor) switching speed in the industry at 1,000 channels/sec. Moreover, even at the fast SRM it can eliminate ion interaction among SRM channels (crosstalk) and makes it possible to analyze multi-target compounds with high accuracies. 2.   High sensitivity achieved with ion accumulation and pulsed ion ejection at short ...

  • JEOL (Europe) BV introduces: Photo Ion-Source for JMS-T200GC AccuTOF GCx
    Electron ionization (EI), generally used for GC/MS and GCxGC/MS analysis, produces fragment ions. Fragments are valuable for database search and compound identification. However, fragmentation adds an additional level of complexity in interpreting complex mixtures, such as crude oil. Some compounds (e.g. alkanes, alcohols) do not produce abundant (or any) molecular ions. Since photoionization (PI) is a softer ionization method than EI, molecular ion can be easily distinguished using this technique. For some analytes, characteristic fragment ions may also be observed. Combining soft ionization with high-resolution exact-mass data and new software tools simplifies processing of complex GC and GCxGC data (e.g. petroleum type analysis). PI provides clear molecular ions and elemental composition that can be combined with EI data to identify unknowns and also provides selective ionization of target compounds The JEOL PI source is designed as a PI/EI combination ion source. Switching between PI and EI can be done without breaking vacuum of the ion source, even without breaking any vacuum. Also during an analytical run it is possible to switch between PI/EI and vice versa. The accurate mass will always stay available whatever ...
