Features
A Unique Ion Source Expanding Your Solutions:
Soft Ionization via EI, CI, and PI
Soft ionization technique can be utilized for qualitative and quantitative analysis
The EI method is a hard ionization method, and many ions are observed, but often a molecular ion is not observed.
The UltraQuad™ 2.0 can utilize PI, CI, and Low-Energy EI as soft ionization methods to observe a molecular ion or ion-adduct molecule
that provides molecular weight information.
The soft ionization method can be applied to the work of confi rming the results of qualitative analysis by library database search and
quantitative analysis by taking advantage of selectivity.
Electron Ionization (EI)/Chemical Ionization (CI) Combination Ion Source (option)
CI is an SI method that provides molecular weight information by reacting with reagent gases. The newly designed EI/CI chamber allows you to switch ionization methods while maintaining vacuum, and the choice of reagent gases provides fl exibility for a wide variety of compounds.

Electron ionization (EI)/Photoionization (PI) combination Ion Source (option)
PI is an SI method using a deuterium lamp. This combination ion source can be used for EI and PI methods. By simply turning on the EI fi lament or PI lamp, the ionization method can be switched instantaneously while maintaining vacuum for effi cient measurement.

Solution for Reliable Quantitative Analysis:
Integrated Analysis + AI Structure Analysis
msFineAnalysis IQ is an optional qualitative analysis software dedicated to the JMS-Q1600GC and JMS-TQ4000GC. "Integrated analysis" provides more accurate analysis results than qualitative analysis based on NIST database search. In addition, even if no promising candidate is found through NIST search, structure estimation can be performed by "AI Structure Analysis".
Integrated AnalysisTo a higher level of qualitative analysis, not limited to NIST search
In addition to NIST search results, the combination of molecular ion information, retention index, and isotope patterns obtained from SI spectra realizes more reliable qualitative analysis.
AI structure AnalysisElucidating the structure of unknown compounds
A mass spectrum library of 200 million compounds generated by AI dramatically accelerates the analysis of unknown compounds. Combined with the molecular weight information obtained from SI, it leads to rapid analysis.
High sensitivity and Excellent dynamic range
Instrument Detection Limit (IDL)
Sequential measurements of OFN 20 fg achieved the IDL 2.6 fg, which is a statistical indicator (guaranteed to be 5 fg or less at the time of delivery*).
*Only when confi gured with an autosampler
Dynamic range
The wide dynamic range of 1.6 × 107 is useful for both quantitative and qualitative analysis of samples with concentration differences.
Calibration curve of OFN (SIM)
Concentration range: 0.005 to 1,000 pg
High-Precision Analysis Not Limited to Helium
Delivers Reliable Results with Nitrogen Gas
To address rising helium prices and increasing supply uncertainty, helium consumption can be significantly reduced by the carrier gas saver and gas switching function. In addition, GC-MS measurement with an alternative carrier gas can be performed simply by changing the setting conditions, and JEOL has a proven track record of measuring with highly safe nitrogen gas, making it suitable for a variety of applications.
Note: There are alternative carrier gases that are not recommended for all preprocessing equipment.
Quantitative Analysis
Analysis of VOCs in water by trap HS-GC-MS using nitrogen carrier gas (MSTips No.416)
Measurements were performed from 1 µg/L for 1,4-dioxane and 0.1 µg/L for other VOCs, and high-sensitivity analysis which suffi ciently met regulatory requirements was achieved even for the nitrogen carrier gas.

Qualitative Analysis
Aroma oil analysis using diff erent carrier gases (MSTips No.444)
The elution positions and EI spectra of all peaks were consistent for both helium and nitrogen, resulting in identical candidate compounds in the database search and the same candidate compounds were obtained. On the other hand, the peak positions and candidate compounds for hydrogen were diff erent, and the EI spectrum was also changed. Because the same molecular ion was detected in the PI spectrum, it is possible that the structural change occurred in the GC inlet and ion source due to the infl uence of the hydrogen carrier gas.
