| The CryoCooled
Peltier Trap can cool samples down to -15°C. It is designed
for use with analytes that do not trap well but can enrich in cold temperatures,
such as some sulfur compounds. The trap is filled with Tenax-GR and silica
gel adsorbents. A vacuum pump is included for drawing samples through the
CryoCooled Peltier Trap. The CryoCooled Peltier Trap has its own power supply,
separate from the main GC power. |
 |
| The CryoCooled
Peltier Trap is basically a heated trap sandwiched between two Peltier coolers.
The CryoCooled Peltier Trap also requires a 10-port gas sampling valve (sold
separately). While the Peltier Trap is enriching the sample, the 10-port
valve is in the LOAD position. At the conclusion of the sampling period,
the trap is heated to 150-200°C and the valve is rotated
to the INJECT position; this places the trap in the carrier gas stream and
sweeps the enriched analytes into the column. |

as enriched by the CryoCooler at -10°C.
