 Scanning Electrochemical Microscope

The SECM employs a highly sensitive, micron-scale tip that can detect very small amounts of electrical current due to the interaction of a mediator in solution and a surface when held within a few microns above the surface.  By moving the tip back and forth across the surface, the electrical signal can be mapped, which can lead to conclusions on the spatial distributions.  Of particular interest in IPRI is the ability to map the performance of plastic solar cells with micron resolution.

Thermal Gravimetric Analyser (TGA)

The TGA (Thermal Gravimetric Analyser) measures the mass of a sample as it is heated at a constant rate in a controlled atmosphere. The atmosphere is typically oxidizing (eg. compressed air) or inert (eg. high purity nitrogen).
