Agilent 7200 QTOF with 7890B GC System - English Introduction

Product Overview
The Agilent 7200 QTOF (Quadrupole Time-of-Flight) coupled with 7890B Gas Chromatograph is the world's first high-resolution accurate mass spectrometer system for GC tandem applications. Designed for high-sensitivity detection and structural elucidation of trace compounds in complex matrices, this system combines the superior separation capability of the 7890B GC with the high-throughput, high-accuracy mass analysis of the 7200 QTOF. It is widely used in food safety, environmental contaminant screening, drug metabolism research, and related fields.

Core Technical Features

1. High-Resolution Accurate Mass Analysis

   • Mass accuracy <5 ppm, resolution >13,000 (at m/z 271.9867), capable of distinguishing isotopic peaks and isomers.
   • Acquisition rate up to 50 spectra/second for precise capture of narrow chromatographic peaks.

2. Advanced Coupling Technology

   • 7890B GC features capillary flow technology (CFT) for multidimensional separation (e.g., heart-cutting, backflushing) to reduce matrix interference.
   • Electronic pneumatic control (EPC) with 0.001 psi pressure accuracy and retention time repeatability <0.008% ensures analytical stability.

3. Comprehensive Fragmentation & Structural Elucidation

   • In-source EI fragmentation combined with MS/MS enables non-targeted screening and molecular formula determination (via MassHunter software).
   • Removable ion source allows rapid switching between ionization modes or maintenance.

Key Applications

• Food Safety: ppb-level pesticide residue detection (e.g., organophosphorus/chlorine compounds) with NIST library matching for rapid identification.
• Environmental Analysis: High-throughput screening of polycyclic aromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs) in complex water samples.
• Pharmaceutical R&D: Metabolite structure identification through MS/MS fragment analysis for functional group determination.

Service Support
3-year core component warranty with method development and data compliance training (meets FDA/EMA requirements).
