EXPEC 236 Headspace Autosampler is a pre-processing device that puts the sample to be tested in a sealed and constant temperature system for gas-liquid or gas-solid equilibrium, and sends the balanced components to be tested to the chromatographic analysis. It has a new design based on static headspace pressurization technology, which realizes solvent-free and efficient extraction of liquid samples and solid samples. EXPEC 236 has the functions of automatic leak detection/multiple extraction/multiple injection, etc. It is easy to operate and maintain, and improves the pretreatment efficiency of complex samples in an all-round way.



  • High sample throughput

Sequential processing of up to 75-position samples, combined with dual moving sample trays and overlapping heating, significantly improves work efficiency.

  • Full inert treatment of the flow path

Low risk of cross-contamination, low loss of components, high reproducibility.

  •  Full process high temperature design

300°C high temperature eliminates cold spots, strong detection ability, and extremely high analytical sensitivity.

  •  Machine reinforcement design

Can be used in stationary and mobile laboratories.

  •  Any combination

Can be used with various brands of GC instruments.

  •  Precision control

Precise gas flow, time, temperature control system, high reproducibility and accuracy of analysis results.

  •  Easy to operate

Automatically complete all process, the results are reliable;

Intuitive visual software interface, easy to operate.

  •  Function assistant

The heating box has a built-in five-level vibration function to accelerate the gas-liquid balance of the sample and shorten the analysis cycle;

Overlap heating function increases sample throughput and saves pretreatment time;

System leak check of the complete flow path to effectively ensure data quality.


Can be used with GC/GC-MS

Medicine, cosmetics, public security investigation, environmental science, energy, material science, light industry packaging, food science,etc.
