Column Editor Kevin Altria explores new websites and shares information about the features of these sites.

By calculating optimal stationary-phase composition and physical parameters, column developers can construct columns that provide the exact separation requirements desired by analysis or current methods.

How can you avoid phase collapse when 5% organic solvent is too strong?

Thermal desorption sampling often provides a means for bringing otherwise intractable samples to a gas chromatography (GC) column for separation and detection.

Capillary electrophoresis (CE) is a useful and versatile technique for a large number of applications. Devoting some discussion to the development of these reported methods to illustrate the separation approaches and strategies to obtain reproducible results, they also compare CE's advantages and disadvantages with those of the more typical method for each type of analysis.

Routine analysis of volatiles from fruit juices can be sampled and concentrated using a static headspace method and rapidly analyzed by high-speed GC.
