AOC-20i/s Automatic Liquid Injection System - Autosampler for GC/GCMS

Designed for gas chromatography (GC) instruments, the AOC-20 Autosampler Series Liquid Sample Injection Systems significantly increase the reliability and operating efficiency of GC analyzes.

The AOC-20 autosampler system is designed for optimal GC injection of liquid samples in any laboratory. Depending on the requirements, the system can be set up for 6, 12 or 150 samples. In addition to the classic GC injection modes, the auto-injector also features on-column injection and multi-injection large volume injection. Parameters can be adjusted to best suit the particular injection mode and sample. Dual Tower system is available to support two injection ports.

As the auto-injector is self-adjusting, it can be easily and quickly removed from the GC for routine maintenance. The newly designed needle-guided syringe holder prevents the syringe needle from bending.

The AOC-20 autosampler series, unlike simple sample injection systems, are multifunctional robotic autosampler systems that make significant contributions to the reliability and efficiency of the analysis. The AOC-20 series features pre-treatment functions such as the efficient addition of solvents that tend to remain in the syringe (including the injection of air or solvent into the syringe prior to sampling), multiple sampling for higher precision analysis of trace compounds, and addition of reaction solvents thanks to continuous injection during analysis. .

Robotic autosamplers for different applications

Different injection modes such as solvent addition and PTV high volume injection are supported.

AOC-20i/AOC-20s










Multiple sample injection (auto injector)

The AOC-20s has a capacity of 150 samples, while the AOC-20i (when used alone) has a capacity of 12 samples.















 


Dual injection system option

Thanks to its compact design, two AOC-20i can be mounted on a single gas chromatograph. Thanks to the light weight of the AOC-20i, it is easy to attach to the gas chromatograph.










 

Flexible sample handling of up to 150 bottles greatly increases laboratory productivity.

The AOC-20s Autosampler carousel and robotic arm provide sample transfer to the AOC-20i Auto-Injector using 1.5mL and 4.0mL bottles. Can understand the difference between vial types by reading the information on the vial tray used. The AOC-20i/AOC-20s is a powerful automation tool for the GC lab that allows the user to take full advantage of the GC system's features.
