Year Founded:

Over the years Entech has continued to perfect the science and art of collecting, storing, and analyzing volatile and semi-volatile chemicals by GC and GCMS. At the heart of this development is Entech’s proprietary Silonite™ surface treatment. Silonite™ renders sampling devices and GCMS sample handling systems as inert as a GC column, providing better recovery of a wider range of compounds than ever before. Silonite™ can be applied to any stainless steel or glass surface, virtually eliminating the adsorption and reactions that can occur on metal and untreated glass surfaces.

Over the past 3 decades, Entech has contributed more to the field of sample preconcentration than any other company. Innovations in sample preparation for GC/MS analysis include:

  • Microscale Purge & Trap
  • Extended Cold Trap Dehydration
  • Large Volume Static Headspace
  • Pulsed Vacuum Extraction
  • Multi-Capillary Column Trapping
  • Vacuum Assisted Sorbent Extraction
