CryoCooled Peltier Trap
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 (not included). 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 150-200oC and the valve is rotated to the INJECT position; this places the trap in the carrier gas stream and sweeps the enriched analytes onto the column. The chromatogram shows the SRI FPD response to 10ppb hydrogen sulfide (H2S) as enriched by the CryoCooler at -10° C.
