An overview of the capabilities of field-flow fractionation coupled with inductively coupled plasma–mass spectrometry and how the technique can separate, detect, and quantitate nanoparticles in environmental matrices.

Micro-Raman spectroscopy has been used to depth-profile a waveguide produced by an ion-exchange reaction in a single crystal of a ferroelectric metal oxide, and to reveal the changes in chemical bonding and atomic structure that occur in this process.

Triple-quadrupole liquid chromatography–mass spectrometry (LC–MS) is one of the most powerful quantitative analytical techniques available for clinical analyses, with recent improvements making it even more appealing to the clinical market. Waters has an extremely strong foothold in the market, but its competitors appear to be stepping up their efforts in the sector. Demand from the clinical industry is rapidly approaching 10% of the overall market for triple-quadrupole LC–MS.

A look at how fluorescent lights are spectroscopically different from the old-fashioned incandescent light bulb.

Guidelines for writing standard operating procedures in a laboratory and best practices for their use.
