ASTM E 1698 Document Information:
Title
Standard Practice for Testing Electrolytic Conductivity Detectors (ELCD) Used in Gas Chromatography
ASTM International
Publication Date:
Mar 15, 1995
Scope:
This practice covers testing the performance of an electrolytic
conductivity detector (ELCD) used
as the detection component of a gas chromatographic system.
This practice is directly applicable to electrolytic conductivity
detectors that perform a chemical
reaction on a given sample over a nickel catalyst surface under
oxidizing or reducing conditions
and employ a scrubber, if needed, to remove interferences, deionized
solvent to dissolve the
reaction products, and a conductivity cell to measure the electrolytic
conductivity of ionized
reaction products.
This practice covers the performance of the detector itself,
independently of the chromatographic
column, in terms that the analyst can use to predict overall system
performance when the detector
is coupled to the column and other chromatographic system components.
For general gas chromatographic procedures, Practice E 260 should be
followed except where specific
changes are recommended herein for the use of an electrolytic
conductivity detector. For
definitions of gas chromatography and its various terms see Practice E
355.
The values stated in SI units are to be regarded as standard. No other
units of measurement are
included in this standard.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
