Agilent 7890A/5975C GC/MSD (G3440A/G3174A) (Refurbished)

The Agilent 7890A Gas Chromatograph (GC) and 5975C Gas Chromatograph-Mass Selective Detector (GC/MSD) systems represent the cutting edge of gas chromatography technology.

Both systems combine robust hardware with advanced software, enabling laboratories to achieve exceptional sensitivity, reliability, and efficiency. Designed for diverse applications, these instruments are suited for trace analysis, complex sample matrices, and high-throughput environments. The integration of features like electronic pneumatic control (EPC), Capillary Flow Technology (CFT), and Retention Time Locking (RTL) ensures reproducible and precise results, while compatibility with advanced autosamplers, such as the PAL system, enhances operational productivity.

The Agilent 5975C GC/MSD further extends capabilities with its high-sensitivity triple-axis detector and inert electron ionization source, enabling detailed qualitative and quantitative analyses for routine and complex samples. Together, the 7890A GC and 5975C GC/MSD systems provide a comprehensive analytical solution, optimized for efficiency, reliability, and advanced performance.

The addition of the PAL autosampler further enhances its efficiency by automating sample handling with precision and reliability.
