The ELCD is an electrolytic conductivity detector, wherein the effluent from the GC is pyrotically converted to an ionizable gas (HX) under reducing conditions. The gas is transported to the reactor cell where a deionized solvent dissolves the gas, thereby increasing the conductivity. The increased conductivity can now be measured and is proportional to the halogen concentration. ELCD detectors may also be used for Sulfur and Nitrogen. As with the XSD detector, it is possible to ventilate the solvent, and halogenated solvents may therefore be used. The ELCD detector is often judged to be somewhat more complicated to run and maintain compared to an ECD. However, the ELCD may well reduce the matrix interferences, and thus false positives, compared to ECD detection. The detector has an extreme linearity on halogens >106
