Semi-Volatile Organic Compounds (SVOC)

​Semi-Volatiles unlike VOCs must undergo some sort of solvent extraction along with agitation, centrifugation and matrix interference removal. Typically environmental samples can use liquid-liquid extraction, solid phase extraction for aqueous matrices. Solids on the other hand generally use pressurized liquid extraction, soxhlet extraction, sonication extraction or supercritical fluid extraction.

For food safety testing, in particular pesticide residues, tradition extraction techniques use the Luke or Mini-Luke method. Since its release, the AOAC 2007.01 and EN 15662:2008 QuEChERS extraction methods have become the preferred technique of choice for this analysis. The QuEChERS method is also finding its way into other contaminants and residues such as mycotoxins and veterinary residues.


The AutoMate-Q40 is a revolutionary system specifically designed and optimized to automate the QuEChERS sample preparation workflow.

The AutoMate-Q40 system automates the following sample prep functions

  • Liquid dispensing/pipetting
  • Vortex mixing
  • Vial shaking
  • Opening/closing sample vials
  • Addition of solid reagents (ex. salts, buffers)
  • Identifying liquid levels
  • Decanting
  • Centrifugation
  • Matrix spiking
  • dSPE cleanup


The system is configured ‘out of the box’ to conduct two of the most popular QuEChERS sample preparation methods:

  • AOAC 2007.01 (Pesticide Residues in Food by Acetonitrile Extraction and Partitioning with Magnesium Sulfate)
  • EN 15662.2008 (Foods of Plant Origin – Determination of Pesticide Residues Using GC-MS and/or LC-MS/MS Following Acetonitrile Extraction/Partitioning and Clean-up by Dispersive SPC – QuEChERS Method)
