GC-EAD interface for gas chromatograph

The application of EAG and SSR signal recording as a detector for active fractions in the effluent of a gas chromatograph (GC) requires a suitable transfer device to apply part of the effluent to the insect preparation without the risk of condensation of compounds. The devices offered by SYNTECH are consisting of a heated transfer line (max. temp. 290 C or resp.) supplied with an air mixing tube assembly and digital temperature controller with power supply. For maximum safety the heater is powered by 24V via an isolation transformer. Mounting plates are provided to attach the transfer line to any model of gas chromatograph.

Two models are available which differ in the length of the heated transfer line.

  • A 300mm long version
  • A 500mm long version (max Temp.: 290 C)

The 300mm long version is suitable for most set ups. For GC-Single Sensillum Recording (GC-SSR) the 500 mm version is more suitable because for this technique a Faraday cage is needed which may reduce the working space.

These two models can be combined with either one of the two available temperature controllers.

  • A version in which the temperature is set manually by the operator
  • A version which follows the actual temperature of the GC-Oven automatically
