Automatic sampler

Liquid injection

Whether standard injections, fast injections, sandwich injections or large volume injections of up to 1000 µl of liquid samples, GC2000 provide highly reliable and efficient operations, allowing you to easily have stable and reproducible analyses result and no cross-contamination or analyte discrimination. The maximum 110-position autosampler is optional, and there is no need for personnel to be on duty during high-throughput injection.

Headspace injection

The software’s overlapping sample preparation function allows pre-processing such as preheating of multiple samples and analysis of GC to be carried out simultaneously to maximize the utilization of the equipment. The headspace needle is constantly heated and continuously cleaned by carrier gas purge during the process to prevent cross-contamination.

Solid Phase Microextraction (SPME)

All steps required for SPME analysis can be fully automated, including fiber tip aging, sample extraction, fiber tip analysis, and fiber tip replacement. Derivatization can be performed directly on the fiber tip or by adding derivatization reagents to the sample prior to extraction. The mechanical stress on the extraction head is greatly reduced, increasing its service life and increasing the uptime of the instrument.

Compared with static headspace, dynamic headspace greatly improves the detection limit, and retains the characteristics of good reproducibility and easy operation of static headspace. Solid sample viscous material and liquid sample headspace are blown away by inert gas, and volatile substances are transferred to replaceable adsorption wells for enrichment, and the entire process is automated GC/MS analysis.
