John Hinshaw discusses computer-controlled pneumatics systems, including their advantages and disadvantages.

The authors present integrated microwave extraction as an enhanced version of microwave-assisted solvent extraction in which solvents are optimized for chemistry and microwave absorption is modified using secondary microwave absorbers.

Dolan reflects on 10 years of change in HPLC and predicts more widespread use of mass spectrometers, faster autosamplers, and better ways of monitoring column health.

The first of two columns on new chromatography columns, accessories, and sample preparation products, including solid-phase extraction, introduced at Pittcon 2002 will feature families/series of HPLC columns new to the marketplace along with detailed coverage of reversed-phase, normal-phase, ion-exchange, and size-exclusion HPLC columns.
