The PLA-GPA1000 fully automatic sampler utilizes precision multi-axis motors to automate the sampling, delivery, and injection processes, standardizing experimental procedures, improving efficiency, and reducing human errors.

During the entire sample delivery process, the PLA-GPA1000 fully automatic sampler is protected by carrier gas, effectively preventing air interference with the gases to be detected (CO, CH₄, H₂, O₂, C₂H₄, etc.) during photocatalytic CO₂ reduction. It is also compatible with mainstream imported and domestic gas chromatographs and can be used in conjunction with headspace samplers.

The injection needle of the PLA-GPA1000 fully automatic sampler uses a high-precision imported Hamilton microsyringe, allowing flexible adjustment of system sensitivity by changing the sample volume through software settings.
