3.1 Electrodes

MME

MME stands for Multi-Mode Electrode and is the working elec-

trode commonly used in the 757 VA Computrace Stand. It com-

bines the most important polarographic and voltammetric mer-

cury electrodes in a single construction:

DME Dropping mercury electrode

SMDE Static mercury drop electrode

HMDE Hanging mercury drop electrode

For installation and maintenance of the Multi-Mode Electrode, see

Hardware Manual.

DME

DME is an electrode mode of the Multi-Mode Electrode and

stands for Dropping Mercury Electrode. It is the classical mer-

cury electrode where the mercury flows out freely from the glass

capillary until the mercury drop is knocked off by a tapping

mechanism after each

Voltage step time

set in the measurement

mode.
