The Agilent/Keysight 18593B is an autoinjector module that automates sample injection into gas chromatographs and HPLC systems. The instrument removes precise sample volumes from vials and delivers them to the GC inlet or column, eliminating manual handling and improving analytical throughput. It combines mechanical precision with software control to streamline high-volume laboratory workflows while minimizing sample consumption.
