JEOL/Agilent GC/TOF-MS JMS-T100GC/7890B System Introduction

Product Overview

The JMS-T100GC/7890B is a gas chromatography-time-of-flight mass spectrometry (GC/TOF-MS) system jointly developed by JEOL (Japan) and Agilent, combining the high-efficiency separation capability of Agilent 7890B GC with the rapid scanning features of JEOL AccuTOF™ high-resolution time-of-flight mass spectrometry. Designed for qualitative analysis and structural elucidation of complex volatile compounds, this system excels in environmental analysis, food safety, and fragrance research, particularly in unknown compound screening and trace contaminant identification.

Core Technical Features

1. Ultra-High Resolution & Mass Accuracy

   • Equipped with a reflectron time-of-flight mass analyzer, achieving resolution ≥10,000 (FWHM, m/z 500) and mass accuracy <1 ppm (with internal calibration), capable of distinguishing isomers with mass differences as small as 0.001 Da (e.g., PCB congeners).
   • High-speed data acquisition (50 spectra/sec) combined with quadrupole ion guide technology enhances sensitivity for low-abundance compounds (fg-level detection).

2. Intelligent GC Compatibility

   • The Agilent 7890B GC features capillary flow technology (CFT), supporting rapid temperature ramping (120°C/min) and precise retention time locking (RTL) to minimize matrix interference.
   • Optional cool on-column (COC) injection or thermal desorption (TD) modules accommodate diverse sample types (solids, liquids, gases).

3. Versatile Data Processing

   • MassCenter workstation enables automated peak extraction, elemental composition calculation (±2 mDa error), and NIST library matching, generating reports compliant with EPA, GB, and other standards.
   • Proprietary isotopic peak fitting algorithms decode complex mass spectra (e.g., halogenated compound cluster ions).

Typical Applications

• Environmental Pollutant Analysis: High-throughput screening of dioxins in air and PAHs in soil.
• Food Flavor Research: Identification of key aroma-active compounds (e.g., thiols) in fragrances.
• Forensic Toxicology: Non-targeted screening of abused drugs and metabolites in blood.

Industry Advantages

Compared to conventional GC/Q-TOF systems, the JMS-T100GC/7890B offers 5x higher mass accuracy without frequent recalibration. Its modular design supports upgrades to comprehensive two-dimensional GC (GC×GC) for ultra-complex sample analysis.

Note: For optimal performance, pair with low-bleed columns (e.g., DB-5MS) and operate in a temperature-stable (±1°C), vibration-free environment.
