Agilent 7890A-5975C Gas Chromatograph/Mass Spectrometer (GC/MS) Introduction

Product Overview

The Agilent 7890A-5975C is a high-performance gas chromatography-mass spectrometry (GC/MS) system that combines the efficient separation capability of the 7890A GC with the high-sensitivity detection of the 5975C single quadrupole mass spectrometer. Widely used in environmental monitoring, food safety, pharmaceutical analysis, and chemical industries, it excels in qualitative and quantitative analysis of trace compounds in complex matrices.

Core Technical Features

1. High Sensitivity & Stability

   • The mass spectrometer is equipped with a three-axis HED-EM electron multiplier, achieving full-scan sensitivity of 1 pg octafluoronaphthalene (OFN) (S/N ≥400:1) and selected ion monitoring (SIM) sensitivity of 20 fg OFN, making it ideal for ultra-trace analysis.
   • The all-inert ion source (max. 350°C) and gold-plated hyperbolic quadrupole minimize adsorption of reactive compounds, ensuring reliable detection of high-boiling-point substances.

2. Versatile Injection & Separation

   • The GC supports split/splitless injection, headspace injection, and cool on-column injection, with Capillary Flow Technology (CFT) enabling multi-channel data acquisition.
   • The MS provides electron ionization (EI) and chemical ionization (CI), supporting full scan (Scan), selected ion monitoring (SIM), and multiple reaction monitoring (MRM).

3. Intelligent Operation & Maintenance

   • Features Retention Time Locking (RTL) and Deconvolution Reporting Software (DRS) for automated method optimization and matrix interference reduction.
   • Sleep/Wake Mode reduces energy consumption by 40%, while Fast Vent Technology minimizes maintenance downtime.

Typical Applications

• Environmental Analysis: Detection of pollutants such as dioxins in air and PAHs in soil.
• Food Safety: Analysis of pesticide residues, food additives, and volatile flavor compounds.
• Pharmaceutical R&D: Identification of metabolites and monitoring of trace impurities.

Industry Advantages

The 7890A-5975C is renowned for its modular design and low maintenance costs. Its helium saver module allows for carrier gas switching, reducing operational expenses. Compared to similar instruments, it excels in mass axis stability (±0.1 amu/48 hours) and scan speed (12,000 amu/sec).

Note: For optimal performance, use high-purity helium (≥99.999%) as the carrier gas and operate in a temperature-controlled (15-35°C), low-vibration environment.
