LCGC North America-06-01-2007

In early 2007, a web-based HPLC columns survey was conducted. Current usage was compared to a 1997 survey.

This month's column brings much of the previous discussion on how to interpret mass spectra to a practical examination of detecting substitutions in counterfeit pharmaceuticals.

lthough liquid chromatography (LC) is most commonly associated with analytical techniques that are found inside the laboratory, LC also has been used in industrial applications for separation of a wide range of products for decades. The technique recently has been applied to requirements in the pharmaceutical and biotechnology industries, both inside the laboratory and in industrial settings. With global sales of over $1.7 billion, the market for preparative LC has encountered a stellar growth over the past few years.

Optimizing peak shape in capillary gas chromatography (GC) is essential for the consistent, accurate analysis of residual solvents in pharmaceutical compounds.

Different methods require different strategies.
