Description

ELCD Capabilities

The Model 5320 Electrolytic Conductivity Detector
(ELCD) is a third-generation ELCD 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 principal 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 specied mode.

•

Quick-change reactor design, disposable resin
cartridge, and reliable solvent system

•

Analog-controlled reactor temperature and
solvent ow

•

Detector base optimized for capillary columns

•

Solvent venting using GC timed-event relay

•

Direct interface with most GC makes and models

•

Direct interface to the OI Analytical Model 4430
PID without a transfer line; the tandem design
occupies only one detector port

•

QA/QC

•

Petroleum Products

•

Process Control, Testing, and Anlaysis

•

Fluorinated and Chlorinated Contaminants in
Process Streams

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
amplies this instantaneous change in conductivity,
producing a signal proportional to the mass of halogen in
the original compound.
