Low current amplifier module

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.
