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 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 Headspace
• Pulsed Vacuum Extraction
