Tekmar 3100 Purge and Trap Concentrator,
Purge and Trap (P&T) has been used for decades to extract
volatile organic compounds (VOCs) from a solid or liquid matrix for
introduction into a Gas Chromatograph (GC) for separation and
identification. The VOCs are concentrated onto an adsorbent trap,
followed by thermal desorption into a GC. Sample matrices can range
from soil, plastics, foods, flavour, fragrance, emulsions and water.
The Tekmar 3100 Sample Concentrator is the "latest and
greatest" in the 3000 Purge and Trap product line. The goal of
any analytical method is to provide precise, reproducible results.
Because the Tekmar 3100 contains an electroform nickel sample pathway,
it provides those results.
This unit has Silcosteel tubing and Silcosteel- treated sample
fittings used throughout the sample pathway. Silcosteel treatment
involves a process that shields active metal surfaces. A thin, silicon
based coating is applied to the metal surface, which keeps analytes
from absorbing onto active sites on the metal. This enhances
inertness, corrosion resistance, and reduced absorption.
The Tekmar 3100 has a redesigned valve oven and mount temperature
control that improves temperature uniformity of the heated sample
