Fully automatic headspace samplerIt is a key supporting equipment for gas chromatography (GC), and its core principle is based on headspace technology: the sample to be tested is placed in a closed container, and volatile components are released from the liquid or solid matrix by heating. After reaching dynamic equilibrium between the gas-liquid or gas-solid phases, the top gas is automatically extracted and injected into the chromatography system for analysis.

　　Fully automatic headspace samplerPerformance advantages and industry value:

Efficient automation:

Batch processing capability: Supports 32-bit sample workstations (some models up to 120 bits), capable of heating 1-3 samples simultaneously, significantly improving throughput.

Fully automated process: from sample loading to cleaning after analysis, without manual intervention, reducing operational errors.

High precision and repeatability:

Temperature control accuracy: ± 0.1 ℃ (such as HS-120 type), ensuring consistency of experimental conditions.

Injection accuracy: The combination design of a six way valve and a quantitative loop results in low dead volume and repeatability RSD ≤ 1.5%.

Flexibility and compatibility:

Customizable parameters: Quantitative tube volume (0.5ml-5ml), headspace bottle specifications (10ml-100ml), and pressurization pressure (0-0.4Mpa) can be adjusted according to requirements.

Wide compatibility: Can be connected to various gas chromatographs at home and abroad, supporting synchronous startup and data collaborative processing.

Reliability and Durability:

Fault self diagnosis function: automatically detects sample bottle position, component faults, and wiring abnormalities to avoid mechanical damage.

Anti corrosion design: using high-strength materials to adapt to harsh environments and reduce maintenance costs.
