Classical methods for protein quantitation rely on colorimetric assays, such as those involving protein-copper chelation (bicinchoninic acid (BCA) and Lowry assays) and dye-binding based detection (Bradford and “660 Assay”) or ultraviolet (UV) spectroscopy.

Although serious Fourier-transform infrared spectroscopy (FTIR) research and core analysis facilities are still alive and well, traditional applications are giving way to more dynamic uses such as controlling processes and field work.

Legally sold as “Vanilla Sky” and “Ivory Wave,” bath salts have become very popular for the very dangerous “high” they are providing.

A much discussed issue related to Near Infrared Analysis (NIR) is the necessity of sample preparation. Ground and unground samples of wheat were analyzed to determine how truly necessary it to homogenize samples before NIR analysis.

Increasingly, analysts perform routine analysis where the action islocations of environmental interest, manufacturing suites, crime scenes, loading docks, and packaging facilities through transportable instruments.
