Agilent GC/MS 6890N-5975B Gas Chromatograph/Mass Spectrometer Introduction

Product Overview

The Agilent GC/MS 6890N-5975B is a high-performance gas chromatography-mass spectrometry system that combines the 6890N Gas Chromatograph with the 5975B Inert Mass Selective Detector (MSD), designed for qualitative and quantitative analysis of trace organic compounds in complex matrices. Widely used in environmental monitoring, food safety, pharmaceutical analysis, and chemical industries, this system delivers reliable and precise analytical results.

Core Technical Features

1. High Sensitivity & Accuracy

   • The mass spectrometer features an inert ion source (EI/CI) with a maximum operating temperature of 300°C, a mass scan range of 1.6–1050 amu, and a detection limit as low as 1.8 pg C/s for octafluoronaphthalene (OFN) in EI mode (S/N ≥20:1 in full scan).
   • The GC is equipped with fourth-generation Electronic Pneumatic Control (EPC), achieving retention time reproducibility of 0.0008 minutes and supporting Retention Time Locking (RTL) for consistent results across instruments, operators, and locations.

2. Intelligent & Efficient Operation

   • Modular design accommodates multiple injection techniques (split/splitless, headspace, purge-and-trap) and detectors (FID, ECD, NPD, etc.), ensuring high flexibility.
   • The built-in 7683B autosampler (100-vial capacity) and ChemStation software enable rapid method setup and compliant data management (21 CFR Part 11).

3. Stability & Safety

   • The MS utilizes a quartz gold-plated hyperbolic quadrupole with independent temperature control to eliminate thermal gradients, ensuring long-term stability (mass axis drift <0.1 amu/48 hours).
   • The GC oven temperature range (4–450°C) accommodates analysis of wide-boiling-point samples.

Typical Applications

• Environmental Testing: Analysis of pesticide residues (e.g., organochlorines, organophosphates) and persistent pollutants in water/soil.
• Food Safety: Detection of food additives, veterinary drug residues, and packaging material migrants.
• Pharmaceutical R&D: Qualitative and quantitative analysis of volatile components in natural medicines and synthetic intermediates.

Industry Advantages

Compared to competitors (e.g., Shimadzu GCMS-QP2020), this system significantly reduces cross-contamination risks with its inert ion source and EPC technology, while its scan speed of 10,000 amu/s makes it ideal for high-throughput laboratories.

Note: Regular ion source calibration and high-purity carrier gas (e.g., helium) are recommended to maintain performance.
