A comparison of electron ionization and soft ionization methods for GC-MS applications Chemical Ionization (CI) Photoionization (PI) Field Ionization (FI)

Automatic structure analysis software for data acquired by electron ionization and soft ionization Designed specifically for GC-HRTOFMS: AccuTOF™ GC-Alpha

In this work, we compare sensitivity levels when using the combination EI/FI and EI/PI ion sources when He and N2 are used as the GC carrier gas.

Pursuing the ultimate in performance and functionality. The JMS-T2000GC AccuTOF™ GC-Alpha Time-of-Flight Mass Spectrometer takes you to a new world of mass spectrometry, the ultimate GC-MS with superior performance and ease of operation.

The JMS-T2000GC  AccuTOF™ GC-Alpha is a superior gas chromatograph - high-resolution time-of-flight mass spectrometer (GC-HRTOFMS) system that simultaneously accomplishes high mass-resolution analysis, high mass accuracy, and high-speed data acquisition, satisfying all your needs for petroleum and petrochemical analyses.

JEOL has developed msFineAnalysis software that integrates both EI and soft ionization data with library search, exact mass, and isotope data.

A gas-chromatograph mass spectrometer (GC-MS) is a combined analyzer that has superior ability in analyzing organic compounds qualitatively and quantitatively. The first part, gas chromatograph, separates the compounds included in a sample (mixture), then the second part, mass spectrometer, obtains mass spectra of the compounds to carry out qualitative analysis. Quantitative analysis can be carried out as well from the peak area of the mass chromatogram of the compound. As a mass spectrometer of a GC-MS system, several types of mass spectrometers are on the market, such as magnetic field, quadrupole (QMS), ion trap (ITD), and time-of-flight (TOF). Each mass spectrometer has its own features and applications.

JEOL has recently announced a 4th generation GC/HR-TOFMS system, the JMS-T200GC AccuTOF-GCx, in 2015. The AccuTOF-GCx offers high sensitivity, high mass resolving power, high mass accuracy, and a wide dynamic range in combination with high-speed data acquisition. In this application note, we show the high sensitivity measurement capability using this latest GC/HR-TOFMS system.
