    VersaSTAT LC

    The LC Low Current Interface is a plug-in, research grade option compatible with many of the Princeton Applied Research potentiostats and galvanostats, designed for the measurement of ultra-low currents with greater accuracy and resolution than the base system.  With the addition of a LC option, the minimum current range is reduced to 4 pA (80 fA with the PARSTAT 4000A) and the current resolution to 122 aA (2.5 aA with the PARSTAT 4000A).

    The LC option can be purchased at any time as a plug-in option.  It consists of an interface cable to connect to the potentiostat and galvanostat, a main body including the high input impedance electrometer and additional current ranges, and the cell leads.  Once attached to the potentiostat/galvanostat users can execute the built in DC Calibration routine.  VersaSTAT 3 users will gain access to the improved E and I Filters as well as additional bandwidth stabilization filters.

    Applications and Software

    The LC is ideal for ultra-low current applications requiring high resolution. 

    Applications involving ultramicroelectrodes, coatings research, corrosion testing of bio-implants, and sensor development are all areas where greater current sensitivity may be needed.
