Overview
This section describes the 3100 Purge and Trap Concentrator, defines its basic functions and system configurations, provides technical specifications, and outlines safety considerations for its use.
Product Description
The 3100 (Figure 1-1) is a purge and trap concentrator that allows automatic processing of liquid and soil samples for analysis by gas chromatography. The concentrator operates and Interfaces with the gas chromatograph (GC) under microprocessor control.
The 3100 is equipped with:
Sample glassware for processing single samples.
A front panel trap pressure gauge that shows the current system pressure (in psi) for each mode.
A front panel LCD screen that displays information about the concentrator's current operating step.
ON/OFF switch on the back panel.
A hand-held controller (purchased separately). The controller consists of a four-line, 20-character wide, LCD (liquid crystal display) and a 30- button keypad. You communicate with the 3100 microprocessor by using the keypad and display screen on the hand-held controller.
Concentrator Functions
The 3100 purges volatile organic compounds from water or soil onto a sorbent trap. The trap is then rapidly heated; the analytes are swept with GC carrier gas onto the column for Separation and detection, as shown in Figure 1-2.
Figure 1-2 3100 Functions
System Configurations
The 3100 concentrator processes a single sample and delivers the resulting analytes to a gas.chromatograph. You may also use the 3100 with other Tekmar-Dohrmann accessories which can extend and enhance 3100 functions. Please refer to the appropriate user manuals for further information.
Tekmar 3100 with Cryofocusing Module
For enhanced sensitivity and chromatographic resolution when analyzing highly volatile compounds on a small bore capillary column, Tekmar-Dohrmann recommends that you use the Cryofocusing Module with the 3100.
Highly volatile components desorbed from the internal trap of the 3100 are refocused and condensed in the trapping area of the Cryofocusing Module as carrier gas goes through the modale to the GC.
The Cryofocusing Module freezes the condensed components in a narrow, cryofocused band on the column.
The Cryofocusing Module is flash heated and flushed with carrier gas to release the analytes on the GC column.

Kurzbeschreibung des Gerätes:
Das Tekmar 3100 ist ein Purge-&-Trap-Gerät, das zur Untersuchung flüchtiger organischer Substanzen aus verschiedenen Matrices genutzt werden kann, wie z. B.
- Kunststoffe und Papier/Karton, wie z. B. Verpackungsmaterialien
- Lebensmittel, Arzneimittel, Aromen
- Boden
- Wasser.
Eine bestimmte Menge der zu untersuchenden Probe wird in einem an dem Gerät fixierten Glasgefäß über eine bestimmte Zeit temperiert, um dann die flüchtigen organischen Substanzen mit dem Gasstrom eines inerten Gases (z. B. Helium oder Stickstoff) aus dem Dampfraum des Gefäßes auszutreiben (Purge, als dynamische Headspace) und anschließend direkt auf einem Adsorptionsmittel anzureichern (Trap).
Die Zeit der Adsorption und die Art des Adsorptionsmittels kann je nach Art und Konzentration der zu untersuchenden organischen Substanzen variiert werden.
Anschließend erfolgt eine thermische Desorption der organischen Substanzen vom Adsorbens. Mit der direkt anzuschließenden Gaschromatographie und einer Detektion wird das zu untersuchende Gemisch organischer Substanzen getrennt und die einzelnen Substanzen analysiert.
Vorteile eines Purge-&-Trap-Gerätes:
- sehr geringe bzw. gar keine Probenvorbereitung
- für etliche EPA-Methoden gefordert
- geeignet für unterschiedliche Matrices
- zur Aroma- und Spurenanalytik geeignet
- sehr hohe Empfindlichkeit, da Probenaufkonzentrierung mittels dynamischer Headspace (aus dem Kopfraum) oder durch Auspurgen bzw. Strippen von Wasserproben erfolgt.
