3.1 Definitions:
3.1.1 dehydration tube—chamber containing concentrated
sulfuric acid that scrubs the effluent gases from combustion to
remove water vapor.
3.1.2 oxidative pyrolysis—a process in which a sample is
combusted in an oxygen-rich atmosphere at high temperature
to break down the components of the sample into elemental
oxides.
3.1.3 recovery factor—an indication of the efficiency of the
measurement computed by dividing the measured value of a
standard by its theoretical value.
3.1.4 reference sensor pair—detects changes in silver ion
concentration.
3.1.5 test titration—a process that allows the coulometer to
set the endpoint and gain values to be used for sample analysis.
3.1.6 titration parameters—various instrumental conditions
that can be changed for different types of analysis.
3.1.7 working electrode (generator electrode)—an electrode
consisting of an anode and a cathode separated by a salt bridge;
maintains a constant silver ion concentration.
