New potential in headspace analysis
Don’t limit your headspace analysis
Previously available headspace syringes may perform poorly when used at high temperatures or cycled
through high temperature. Common problems experienced with headspace analyses due to poor syringe
performance include: syringe plunger tips failing; leaking syringes; needles detaching; additional sample
flushing due to high syringe carryover; and worst of all, poor reproducibility of results.
Introducing the new standard in headspace syringes that overcomes these problems.
Outstanding Reproducibility
• SGE’s unique energized plunger tip design ensures a gas tight seal is consistently maintained
providing outstanding performance (%RSD) with temperature cycling.

• Improved sample and solvent compatibility:
- The PTFE plunger tip in Diamond Headspace Syringes enables the use of a broader range of
samples and solvents compared with polymers used in plungers of other high temperature
syringes, this provides greater flexibility for your headspace analyses and a longer lasting syringe.
Save Time and Improve Headspace Analysis Workflow
• Improved workflow:
- SGE’s Diamond Headspace syringes maintain performance up to 150 °C enabling you to improve
your workflow by avoiding the need for transfer lines or a dedicated headspace autosampler.
• Save time:
- Diamond Headspace syringes do not require extended equilibration time unlike other
headspace syringes.
- Reduced carryover of Diamond Headspace syringes reduces the need for flushing and
washing of syringes.
There is no dead space on the SGE syringe.
Sample is completely swept from the barrel.
This image also shows SGE's unique energized
plunger tip which ensures reproducibility
by maintaining a complete seal against the
internal surface of the syringe.
