Higher limits in Headspace Analysis

• Outstanding reproducibility maintained during temperature cycling.
• Highest operating temperature available.
• Save time and improve analysis workflow.

Until now, Headspace syringes had the potential to perform poorly when used at high temperatures. Common problems experienced with Headspace analysis due to poor syringe performance include: syringe plunger tips failing; leaking syringes; needles detaching; additional sample flushing required due to high syringe carryover; and worst of all, poor reproducibility of results.

Diamond Headspace Syringes - the new standard in Headspace syringes overcome these problems.

The unique energised plunger tip design ensures a gas tight seal is consistently maintained providing the lowest syringe carryover and outstanding reproducibility.

Diamond Headspace Syringes have the highest operating temperature, maintain performance of up to 150°C and continue to perform with temperature cycling resulting in increased Headspace Syringe lifetime.

• Outstanding reproducibility: The energized plunger tip design ensures a gas tight seal is consistently maintained providing outstanding
  performance (%RSD) with temperature cycling and high temperature (see figure 1).
  
  
• High Operating Temperature: SGE’s Diamond Headspace Syringes maintain performance up to 150 °C and continue to perform with temperature cycling resulting in an increased headspace syringe lifetime. A series of 150 injections of samples with an incubation temperature set at 140 °C and a syringe temperature of 150 °C was realized. The whole sequence last more than 20 hours (see figure 2 below).
  
  
• 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.
• 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.
• No dead space: There is no dead space on the SGE Diamond Headspace syringe. The sample is completely swept from the barrel (see figure 3 on the right).

Diamond Headspace syringes are currently available for CTC Analytics GC autosamplers, and Thermo Scientific RSH GC Autosamplers in 1 mL, 2.5 mL and 5 mL.
