MEASUREMENT OF SEMI-VOLATILES IN WATER

Safe, efficient sample preparation workflows of water monitoring

Sample preparation for SVOC analysis in water often depends on liquid-liquid extraction, a time-consuming process that is difficult to reproduce and exposes staff to hazardous solvents such as dichloromethane. Manual handling further increases variability, especially when dealing with complex matrices, making it harder to achieve strict regulatory limits in workflows such as EPA 8270 or 3511.

Streamline SVOC sample preparation through full automation

The ePrep® ONE reduces hands-on time, solvent exposure and process variability. Key features include:

  • Fully automated sample preparation for EPA 3511 (8720) workflows with direct output to vials
  • Highly efficient and reproducible syringe liquid-liquid extraction
  • Smaller sample volumes, drastically reducing the use of solvents
  • Automated liquid-liquid extraction (ALLEx) for fast, consistent mixing without manual shaking
  • Sealed vial handling that protects both the sample and the analyst from exposure
  • Stand-alone operation, for efficient preparation of GC or LC samples for any brand of instrument
  • Capable of processing 200-250 samples per day

An efficient workflow for real-world applications

ePrep has developed a workflow based on EPA Method 3511, which allows the use of smaller sample volumes and supports safer, more efficient analysis. You can learn about this in these application notes, available in both short and extended formats.
