Attenuated total reflection flow cell

This invention uses prisms to couple infrared radiation into a double-side polished wafer that serves as the internal reflection element (IRE) for attenuated total reflection (ATR) spectroscopy using a flow cell. ATR flow cells are used for flow chemistry, biology/biotech, electrochemistry,...

BROADBAND MICROWAVE PHASE SHIFT DETECTOR

The new NIST detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a change in effective dielectric constant of the sample. The major...
