Equipped with a three-channel independent temperature control system and programmable automatic operation, it can store 20 methods and simultaneously activate the chromatography. Supports 12 20mL head-space vials, ensures high injection repeatability, and features continuously adjustable pressure and flow rate for convenient and reliable operation.
The Automatic Head-space Sampler features independent three-zone temperature control (±0.2°C), programmable automation with 20 user methods, and synchronization with GC/workstations. It accommodates 12 vials (20mL), ensures high repeatability (RSD ≤1.0%), and offers adjustable injection pressure (0–0.4 MPa) and configurable back-flush cleaning.
Precise & Independent Temperature Control: Features three-zone independent heating (vial, injector, transfer line) with an accuracy of ±0.2°C for highly reproducible sample incubation and transfer.
High Injection Repeatability: Ensures reliable results with an injection repeatability of RSD ≤1.0% (for 200ppm ethanol/water).
Automated & Programmable Operation: Supports programmable time/event sequences, storage of 20 user methods, and synchronization with GC/workstation for true walk-away automation.
Efficient Sample Throughput: Accommodates 12 standard 20mL vials (other sizes customizable) for batch processing.
Stable & Flexible System Control: Offers adjustable injection pressure (0-0.4 MPa) and configurable back-flush cleaning to maintain system integrity and prevent carryover.
