Entech Instruments is a leading developer and manufacturer of analytical instrumentation that supports professionals around the world in the Environmental, Industrial Hygiene, Food & Beverage, Product Testing, Forensic, and Clinical Analysis markets.

We specialize in the creation of inert sample collection equipment as well as GC and GC/MS sample preparation and introduction technologies. Many of these products feature Silonite®,
our proprietary ceramic coating that is designed to render stainless steel tubing, canisters, and other sampling equipment as inert as a GC column.We provide our customers with complete solutions and support for “analytical grade” air monitoring products and headspace GC/MS inlet systems that can sample, store, and recover virtually all gas chromatography compatible compounds.

Over the past 2 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 Headspace
  • Pulsed Vacuum Extraction

and recent advancements in Large Volume SPME (LV-SPME). LV-SPME uses SPME cartridges for increased sampling and desorption rates to achieve part-per-quadrillion detection limits for many taints and off flavor compounds.
We support direct thermal desorption, as well as other techniques that can further extend the range of recoverable analytes when compared to thermal desorption alone.
