Low Input Bias Current Op Amps (≤100 pA)
-
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

Potential Meters
-
Potential meters are basically electrometers which have extremely high input resistances in order to keep the feeding reference electrode free of load. This is necessary to maintain the true potential. pH - meters can be used as potential meters when fast reading is not required, because common pH meters are very slow. When the potential answer to current pulses is to be followed, potential meters are essential.

Single Channel Potentiostats
-
Potentiostats control a voltage and measure a resulting current. The Control Amplifier outputs power to the counter electrode (also called auxiliary electrode). A feedback loop is established to control the cell potential between the reference and working electrode. This voltage is measured by the input electrometer, that has a high impedance. This current is then measured between the working and counter electrodes while this potential is maintained at the working electrode and reference electrode.

Scanning Electrochemical Systems
-
The VersaSCAN is a single platform capable of providing spatial resolution to both electrochemical and materials-based measurements. Each VersaSCAN is based on a common high-resolution, long-travel, closed-loop positioning system mounted to a vibration-resistant optical base. Different auxiliary pieces are mounted to the positioning system. These ancillary pieces (e.g., an electrometer, piezo vibration unit, or a laser sensor) provide functionality to the positioning system for different scanning probe experiments. VersaSTAT potentiostats and Signal Recovery Lock-in Amplifiers are integrated via ethernet control to make accurate measurements of these small signals.

Femto / Picoammeter and Electrometer / High Resistance Meter
B2980A Series
-
Both the picoammeters and electrometers provide a world-best performance of 0.01 fA (0.01 x 10-15 A) current measurement resolution. In addition, the electrometers can measure resistance up to 10 P (10 x 1015 ), which is also a best-in-class specification. Finally, since AC power line noise can be difficult to eliminate when making low-level measurements, both the picoammeters and electrometers are available in battery powered versions.

Localized Electrochemical Impedance Spectroscopy
VS-LEIS
-
The VersaSTAT 3F applies an AC voltage to the sample emerged in electrolyte. This "global" voltage generates AC current to flow at the electrode / electrolyte interface. A dual-element probe is positioned in solution close to the surface of the sample. The electrometer measures a differential voltage measure between the two measurement elements as a measure of local voltage-drop in solution. This voltage-drop exists in solution because of current flow from local reactions at the sample, the resistance of the electrolyte and the spatial separation of the dual measurement elements.
