Agilent 7890B/7200Q-TOF GC/Q-TOF MS System Introduction

The Agilent 7890B/7200Q-TOF GC/Q-TOF MS system represents Agilent Technologies' premium analytical instrument, combining the 7890B gas chromatograph with the 7200 quadrupole time-of-flight mass spectrometer (Q-TOF) to deliver state-of-the-art GC/MS performance. This system innovatively integrates the high-efficiency separation capability of gas chromatography with the high-resolution, high-sensitivity detection advantages of Q-TOF mass spectrometry, providing a powerful tool for complex matrix analysis, unknown compound identification, and non-targeted compound screening.

Core Technical Features

The system features an orthogonal time-of-flight mass analyzer design equipped with three turbo molecular pumps and a hexapole collision cell, delivering a mass range of 20-1700 Da with resolution up to 40,000 FWHM and mass accuracy <5 ppm. The innovative Removable Ion Source (RIS) technology enables rapid switching between EI and CI modes with minimal vacuum loss. The 32 G/s high-speed data acquisition rate coupled with a 4 GHz analog-to-digital converter achieves high-sensitivity detection in full scan mode, with a dynamic range up to 10^5. The system incorporates a vacuum-insulated INVAR flight tube that effectively eliminates mass drift caused by temperature fluctuations, ensuring 24/7 mass stability.

System Advantages and Applications

The 7200 Q-TOF's unique MS/MS capability is realized through quadrupole mass filtering and hexapole collision cell, providing rich structural information. Compared to traditional triple quadrupole instruments, it offers comparable sensitivity but higher resolution, simultaneously acquiring accurate mass data and fragment ion spectra. The system finds extensive applications in metabolomics, food safety (pesticide residues, illegal additives), environmental pollutant screening, forensic toxicology, and new material research. For complex matrix analysis, its high resolution effectively distinguishes co-eluting compounds, while accurate mass measurement significantly improves compound identification accuracy.

Intelligent Operation and User Convenience

The system comes with MassHunter workstation software featuring integrated method development tools and automated data processing functions. Retention Time Locking (RTL) technology ensures highly reproducible results across different instruments. The innovative sleep/wake mode significantly reduces standby energy and carrier gas consumption, while early maintenance feedback helps prevent unexpected downtime. Supporting comprehensive analytical needs from routine screening to in-depth research, this system stands as the ideal choice for solving the most challenging analytical problems.
