JEOL introduces the InfiTOF Spectrometer JMS-MT3010HRGA

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.
