ECD - Extreme low currents
The lowest current range available on the standard Autolab is 10 nA. At this current range, the Autolab has a current resolution of 30 fA. When doing measurements on micro-electrodes sometimes even higher resolution is needed. Originally designed for electrochemical detection in HPLC and FIA, the ECD module makes the measurement of such low currents possible.
The ECD module provides 2 additional current ranges of 1 nA and 100 pA giving a minimum current resolution of 0.3 fA. The ECD module also has a built in third order Sallen-Key filter, with 3 RC-time constants that help to filter out noise.
