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

System Overview

The Agilent GC/MS 7890A-5975C is a high-performance gas chromatograph-mass spectrometer system developed by Agilent Technologies, consisting of a 7890A gas chromatograph and a 5975C mass spectrometer detector. Renowned for its exceptional sensitivity, stability, and user-friendly operation, this system finds extensive applications in environmental monitoring, food safety, pharmaceutical analysis, and forensic toxicology.

Technical Features

The 7890A gas chromatograph incorporates advanced Electronic Pneumatic Control (EPC) technology, enabling precise flow and pressure control with excellent retention time reproducibility. The column oven temperature ranges from ambient +4°C to 450°C with a maximum heating rate of 120°C/min, meeting the separation requirements of various complex samples.

The 5975C mass spectrometer features an inert ion source design with femtogram-level (fg) detection limits, a mass range of 1.6-1050 amu, and a maximum scan rate of 12,500 amu/s. The innovative hyperbolic quadrupole mass analyzer provides superior mass resolution and stability. The standard inert ion source and transfer line effectively reduce adsorption and decomposition of reactive compounds.
