Unlike syringe injection systems, the loss of headspace vapor during the injection process due to vapor pressure changes is never a concern. In addition to the sensitivity benefits of the Dynamic Headspace technology, the Headspace Auto Sampler delivers the added flexibility of performing traditional fixed loop injections and time-based injections incorporated within a single system. Whether your preference is to make a highly reproducible timed injection to minimize the number of sample pathway components, a known/fixed volume loop injection or a concentrated injection for improved sensitivity, the Headspace Auto Sampler is the right instrument for you.

Productivity:
  • Horizontal rotary evaporation cuts equilibration times by 80%
  • High-capacity 90-position sample carousel
  • Automatic leak and integrity check
