All studies represented by the chromatogram below have been conducted utilizing Vacuum Assisted Sorbent Extraction & Headspace Sorbent Pens™

The most versatile extraction and sample preconcentration technology available for GC and GCMS systems. Sorbent Pens™ combine the features of SPME and classical ¼” adsorbent traps in a design with far more flexibility and enhanced performance. The Sorbent Pen™ uses an entirely new approach for sample extraction.
