Fully Integrated Systems: Autosampler and GC are designed by the same manufacturer. Seamless control through a unified software interface.
Modular/Third-Party Autosamplers: Can be connected to different GC brands. Require compatibility validation and possibly third-party drivers or interface modules.
Liquid Autosamplers: Standard type used for injecting liquid samples from vials.
Headspace Autosamplers: Sample volatile compounds from the gas phase above a liquid or solid in sealed vials.
SPME Autosamplers: Use Solid Phase Microextraction fibers to extract analytes, followed by direct thermal desorption in the GC inlet.
Robotic Systems: Offer advanced automation with multiple techniques (e.g., shaking, heating, derivatization), often used in high-throughput or QA/QC labs.
