Inddampning og opkoncentrering

The GERSTEL Multi-Position Evaporation Station (mVAP) performs solvent evaporation enabling automated sample concentration for lower detection limits as well as solvent exchange for improved chromatography and LC/MS ionization.

Up to 196 samples in standard autosampler vials can be concentrated in batches of up to six. Concentration is performed at a user defined temperature, agitation and vacuum for best possible protection of the samples.

Many combinations

Concentration in the mVAP can be combined with a wide variety of sample preparation and clean-up techniques such as SPE, dispersive SPE (DPX), liquid/liquid extraction or filtration with the significant benefit of automated injection of the concentrated sample into a GC/MS or LC/MS system. Every step is controlled by mouse-click using the MAESTRO PrepBuilder. Just one method and one sequence table is needed for the entire process including GC/MS or LC/MS analysis.


mVAP features and benefits:

  • Efficient concentration of extracts and solutions under controlled conditions, user defined temperature, vacuum and agitation levels
  • Improved limits of detection
  • Solvent exchange for GC/MS or LC/MS analysis
  • Concentration in combination with all GERSTEL techniques
  • Reliable results
  • Reproducible sample preparation through uniform processing of all samples, better RSD
  • Condensation-free and safe removal of solvent vapors
  • Contamination-free through use of sealed autosampler vials, staff exposure is minimized
  • All liquid transfer is automated
  • Automated loading of 2 mL, 4 mL and 10 mL vials into mVAP
  • Parallel evaporative concentration of up to six samples
  • PrepAhead ensures preparation of up to six samples simultaneously with the analysis on the GC/LC
