Agilent 5977A Series GC/MSD System - Data Sheet

Significance of the topic

Gas chromatography–mass spectrometry (GC/MS) remains a cornerstone technique in analytical chemistry, offering unparalleled sensitivity and specificity for trace-level detection. The integration of advanced GC and mass selective detector designs addresses growing demands in pharmaceuticals, environmental monitoring, forensics, and petrochemical analysis. Enhancements in reproducibility, productivity, and environmental performance directly impact laboratory efficiency and data confidence.

Objectives and Overview

This data sheet presents the Agilent 5977A Series GC/MSD system, designed to build on decades of innovation by combining the reliable Agilent 7890B gas chromatograph with the high-sensitivity 5977A mass selective detector. Key aims include improved detection limits, robust workflow tools, streamlined method development, and reduced operational costs through eco-friendly features.

Methodology and Instrumentation

The system couples precise pneumatic and temperature control of the 7890B GC with the rugged 5977A MSD. Core instrument components include:

• Noncoated Inert Extractor EI ion source (10 fg OFN IDL) and optional CI modes
• Heatable monolithic quartz gold quadrupole (up to 200 °C)
• Triple Axis Detector to minimize neutral noise
• Scan speeds up to 20,000 u/s and dynamic range up to 10^6
• Agilent TwisTorr 304 FS turbo pump and optional dry pump for oil-free vacuum

Sample introduction is supported by capillary flow technology, split-splitless and multimode inlets, and various autosamplers. Method development and data processing leverage MassHunter Acquisition and Data Analysis software alongside classic ChemStation tools.

Main Results and Discussion

Performance verification demonstrates exceptional sensitivity and stability:

• Instrument Detection Limits of ≤10 fg OFN in SIM mode
• Scan mode signal-to-noise ratios exceeding 1500:1
• Robust performance across EI, PCI, and NCI ionization methods
• Mass axis stability better than 0.10 u over 48 hours

Ease-of-maintenance features, such as tool-free inlet liner replacement and rapid source removal, minimize downtime. Automated Sleep modes and direct GC/MS communication reduce power and gas consumption without compromising performance.

Benefits and Practical Applications

The 5977A GC/MSD system delivers:

• Ultra-low detection limits for trace analysis in environmental, forensic, pharmaceutical, and food testing
• High reproducibility via inert sample pathways and precise pneumatic control
• Flexible workflow with synchronized SIM/scan acquisition and extensive spectral libraries
