USED AGILENT - KEYSIGHT 7890B

The Agilent 7890B GC System with the 5977B Mass Selective Detector (MSD) is a high-performance gas chromatography–mass spectrometry (GC-MS) platform designed for qualitative and quantitative analysis of volatile and semi-volatile compounds. When equipped with an automated Headspace Sampler, the system provides a complete solution for the analysis of volatile compounds in pharmaceutical, environmental, food, forensic, petrochemical, and industrial laboratories.

The 7890B GC features electronic pneumatic control (EPC) for precise gas flow management, while the 5977B MSD incorporates an Extractor ion source, high-efficiency quadrupole analyzer, and Hydrogen Sensor for enhanced sensitivity, reliability, and simplified maintenance. The automated Headspace Sampler enables reproducible sampling of volatile analytes with minimal sample preparation and high-throughput operation. The system is controlled through Agilent MassHunter™ software. (Agilent 5977B GC/MSD brochure)
