Gerstel Headspace

Headspace

The GERSTEL MPS configured as Headspace Autosampler provides the analyst with a highly productive tool for performing GC Headspace analysis. The MPS is perfectly suited for routine analysis and for R&D applications that demand a higher degree of flexibility.

Due to the modular concept, the MPS easily adapts to individual requirements in the laboratoty:

  • The Cooled Agitator spans a temperature range from 10oC to 200oC enabling analysis of thermally labile samples such as foods.
  • Headspace sampling from the tray combined with thermostated trays provides capacity enhancement
  • The Headspace purge tool enables true MHE analysis and method validation
  • The MPS Agitator Stirrer (AS) operates in agitation mode or in stirring process prior to headspace sampling, thereby improving throughput and reproducibility. The stirring mode is especially useful for Headspace SPME applications.
