The OI Analytcal 5320 Electrolytic Conductivity Detector (ELCD) excels at selectively detecting halogenated compounds, while demonstrating its flexibility by offering detection of sulfur and nitrogen.
The Model 5320 ELCD detector is designed for highly sensitive measurement of halogenated compounds.
The detector converts halogenated compounds eluting from a GC column into an ionizable gas (HX) using reductive conditions in a high-temperature catalytic microreactor.
Gaseous reaction products carried into the detector cell dissolve in a deionized solvent, increasing the electrolytic conductivity of the mixture.
The detector amplifies this instantaneous change in conductivity, producing a signal proportional to the mass of halogen present in the original compound.
Interfacing an ELCD detector with a PID as tandem detectors is prescribed by USEPA Methods 502.2 and 8021 for the measurement of chlorinated and aromatic volatile organic compounds in drinking water and wastewater samples.
