resulting from the presence of a solute in the column eluent sensor cell is amplified and recorded. The sensitivity of the detector was similar to that of the katharometer i.e. about 1 x 10-6 g/ml. Unfortunately, the practical lifetime of this detector was also relatively short as it was eclipsed by both the FID and the argon ionization family of detectors subsequently introduced by Lovelock. The Emissivity Detector Another interesting early detector was the emissivity detector developed by Grant. an interesting and innovative extension of the flame thermocouple detector.
