Description
Agilent 7890A GC with 5975C Inert XL EI/CI MSD & 7693 Autosampler
The Agilent 7890A GC with 5975C Inert XL EI/CI Mass Selective Detector (MSD) and 7693 Autosampler is a high-performance analytical platform designed for reliable qualitative and quantitative analysis of volatile and semi-volatile compounds. Commonly referred to as a GCMS system, this configuration combines precise gas chromatographic separation with advanced mass spectrometry detection, enabling confident compound identification in complex matrices. The 5975C Inert XL MSD enhances performance for active and trace-level analytes by minimizing surface interactions and improving signal stability, making it well-suited for demanding applications. The system supports both Electron Ionization (EI) and Chemical Ionization (CI) modes, allowing flexible analytical workflows. EI provides highly reproducible fragmentation patterns for library matching, while CI enables softer ionization for molecular weight confirmation and structural insight.
Paired with the 7693 Autosampler, the system offers automated, high-precision sample introduction, improving reproducibility and enabling efficient batch processing. This integration reduces operator variability and supports high-throughput laboratory environments. Built on the proven 7890A platform, this system delivers consistent thermal control, robust performance, and seamless compatibility with Agilent software for data acquisition and analysis. It is widely used in environmental testing, pharmaceutical analysis, food safety, forensic investigations, and chemical research laboratories.
