GC-Syringes CTC Headspace®

Point Style 2 (pst2):
12° bevelled non-coring needle point recommended for septum penetration. Ideal for gas chromatographic applications.

Point Style 3 (pst3):
Blunt needle point (90°) for use with HPLC injection valves. Also recommended for applications where exact dosing is required (e.g. thin layer chromatographs).

Point Style 4 (pst4):
10-12° bevelled needle point recommended for life science applications; sharp point for animal imjektion.

Point Style 5 (pst5):
Conical needle with side port for penetration of septa, thin-gauged vinyls and plastics without coring; minimizes septum damage

Point Style AS (pstAS):
Special conical style needle point (8° taper) designed to
withstand the demands of multiple injections; exclusively used on
GC autosampler syringes
The new High Dynamic (HD-) plunger has been optimised for higher throughput in the headspace technique. This headspace syringe has been designed for the CTC PAL autosampler system. Modern GC Headspace analysis requires injecting over large temperature ranges. Traditional headspace syringes are composed of rubber O-ring sealed plungers which have a limited sealing performance at high temperatures.
Advantages:
- New sealing system based on a novel metal spring allows working with enhanced tightness
- Excellent performance over a large temperature range and temperature gradients
- Increased life-time compared to traditional headspace syringes
- Increased accuracy and reproducibility of headspace GC analysis
