Entech Instruments is a leading developer and manufacturer of analytical instrumentation that supports professionals around the world in the Environmental Monitoring, Industrial Hygiene, Food & Beverage, Product Testing, Forensic Investigation, and Clinical Analysis markets. We specialize in the creation of inert air and gas sample collection equipment as well as GC/MS sample preparation and introduction technologies.

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

History of Entech

1990 - First Product Delivery

Delivered The First Automated Air Preconcentrator For Multi-Sample Analysis (Model 2000)

1991 - First Solution for Method TO-14

Introduced the first complete solution for EPA Method TO-14 SUMMA Canister Application (Analysis, Cleaning, Stds).

1992 - First combined Polar/Non-Polar

Created the first combined polar/non-polar VOC solution (Microscale Purge & Trap) a few years before EPA TO-15 was introduced.

1994 - 2nd Gen Preconcentrator

Introduced Entech’s 2nd Generation Preconcentrator (Model 7000) after 4 years of field data from model 2000.

1995 - Smartlab

Introduced complete SmartLab product line to integrate entire air analysis laboratory onto a single Windows PC.

1996 - Asia & Europe Expansion

Increased distribution network to include Asia and Europe.

1998 - 7100 Preconcentrator

After 4 years of feedback from 7000, Entech implements major improvements.

2001 - Headspace

Introduced first canister / large volume headspace robotic system (7524)

2002 - Introduced SmartLab 2
