A 1.0 mL gastight syringe with a PTFE plunger tip and Luer Tip Cemented needle termination, designed for the CTC PAL System Combi PAL-xt and Combi PAL-xt Extended autosamplers. Features a unique spring-in-plunger design that maintains a leak-free seal across temperature ranges up to 110°C, improving reproducibility and lifetime compared to conventional O-ring sealed syringes. The syringe uses a 26-gauge needle and is optimized for headspace sampling in gas chromatography applications.
Modern GC Headspace analysis requires injecting over large temperature ranges (e.g. ITEX analysis). Traditional headspace syringes come with a rubber O-ring sealed plunger which has a limited sealing performance at high temperatures. The high dynamic HD-Type syringe employs a unique spring in the plunger tip which compensates for the materials’ different expansion coefficients, creating a better seal over a larger temperature range, and it also improves lifetime.
