ELECTROLYTIC CONDUCTIVITY GC DETECTOR The 5320 Electrolytic Conductivity Detector (ELCD) is designed for selective detection of halogen-containing compounds. The 5320 ELCD consists of three principal components: the reactor assembly, the cell-solvent assembly, and the detector controller. The ELCD's primary mode of operation is the halogen mode (X); sulfur (S) and nitrogen (N) modes are also available. Each detection mode kit contains all of the required materials (except the solvent) to operate the ELCD in the specified mode. Operating Principle The ELCD converts halogen compounds eluting from a GC column to an ionizable gas (HX) using reductive conditions in a high-temperature catalytic microreactor. Gaseous reaction products carried into the detector cell become dissolved in a deionized solvent, which increases the electrolytic conductivity of the mixture. The detector amplifies this instantaneous change in conductivity, producing a signal proportional to the mass of halogen in the original compound. ELCD Capabilities • Quick-change reactor design, disposable resin cartridge, and reliable solvent system • Analog-controlled reactor temperature and solvent flow • Detector base optimized for capillary columns • Solvent venting using GC timed-event relay • Direct interface with most GC brands and models • Directly interfaces to a 4430 PID without a transfer line to form a tandem detector that requires only one detector port Principal Applications • USEPA Methods (502.1,502.2, 601,608, 611,8010, 8021) • VOCs • Pesticides • Halogenated Compounds • QA/QC • Petroleum Products • Process Control, Testing, and Analysis • Fluorinated and Chlorinated Contaminants in Process Streams Ol-Analytical Spa xylem brand
