Scanning Probe Microscopy/Atomic Force Microscopy (SPM/AFM Analysis)
Rocky Mountain Laboratories, Inc.
Scanning probe microscopy (SPM) refers to a family of measurement techniques that utilize a scanning probe. The most common measurement is Atomic Force Microscopy (AFM Analysis), which measures surface topography. Imaged areas can be from the nm scale to as large as 100 µm X 100 µm. Heights and depths of features can be measuredand many surface roughness parameters, e.g Ra, can be calculated. 3-D images can also be produced for dramatic data presentation. Magnetic and electrical response can also be measured with SPM.

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.
