​​​About The Technique
The 3100 Sample Concentrator purges volatiles from a solid or liquid matrix onto a sorbent trap. This trap is then rapidly heated and the analytes swept with GC carrier gas onto the GC column for separation and detection. 

Automation and Versatility
The Tekmar 3100 can be interfaced to virtually any GC or GC/MS system. It can be used as a base instrument for controlling a complete selection of automatic samplers to meet the demands of a variety of laboratories. Integrating Into Your Lab Data System Environment Tekmar's TekLink™ software permits total method control of the 3100 through the Windows. It provides an effective and efficient way to transform the instruments in your laboratory into an integrated analytical system. 

Trap Pressure Control
Trap Pressure Control (TPC) exerts an adjustable pressure on the trap during the purge cycle, which results in the light gases condensing more readily on the adsorbent. The analytes do not travel as far into the adsorbent and are adsorbed in a tight band. This smaller band of analytes is transferred to the GC column resulting in sharper peaks. Performance benefits include an improved signal-to-noise ratio, increased sensitivity and outstanding resolution. TPC allows the user to monitor pressures during each mode and to quickly check for obvious leaks in the system.​
