Speciation analysis by LC-ICP-MS has been growing rapidly in popularity and application over the past several years. Not only have people begun looking at different elements and species, but there has also been an increase in the variety of matrices that speciation analysis is being performed on.

Good vacuum system design is a crucial underpinning for high performance instrumentation. The important aspects of pressure and vacuum need regular teaching, and here Ken Busch discusses them.

The new FDA Commissioner wants a strong FDA and is backing her words with action by initiating a program that cuts the time that firms must respond to 483 observations from 30 to 15 business days. Not only is the time halved but the response must be complete. Therefore it is better and cheaper to be compliant than not.

A small niche market within fluorescence spectroscopy is portable fluorometers. Primary applications are in the agricultural industry, but there is considerable potential elsewhere. The market landscape is small and fragmented, with no dominant leader, and significant potential for growth.

The interaction of indigo carmine with nucleic acids in weak acid medium was studied in the presence of cetyltrimethylammonium bromide (CTMAB) using resonance light scattering, UV–vis, and NMR.
