Gas Chromatography (GC)

To meet system suitability requirements, chromatographers might need to make adjustments to the high performance liquid chromatography (HPLC) operating conditions.

LECO Corporation (St. Joseph, Michigan) has introduced a series of Separation Science e-Seminars for fall 2009 designed to give scientists information on several new chromatographic techniques.

The causes and cures for peak tailing are discussed, along with the various ways that chromatographers measure tailing peaks.

John Hinshaw takes a break from the technical and visits a number of chromatography forums and discussion groups.

Ron Majors provides first-hand coverage of some of the technology and application advances reported at HPLC 2009.

The former "Milestones in Chromatography" editor returns to give readers the story of his time in the field.

Two of the 2009 R&D 100 awards have been awarded to Phenomenex for the company?s gas chromatography products.

Guest columnists explore how ionic liquids can be tweaked to mimic the popular stationary phases of today.

The separation of structurally diverse analytes is often complicated by chance coelutions with other analytes or with matrix related compounds. Often the column is blamed, but while such coelutions make analysis difficult they do not necessarily indicate a faulty column, poor chromatography or method design.

John Hinshaw discusses the effects that peak tailing has on quantitative measurement of peak height and area.

Doug Kitson looks at some of Poland's leading separation science groups.

Malvern Instruments (Westborough, Massachusetts) has more than doubled the size of its web seminar program.

ACD/Labs (Toronto, Canada) announced the release of new software for target analysis of complicated LC?MS and GC?MS datasets, without the tedious and difficult manual interpretation.

French scientists have developed a GC?MS method, combined with a triple partition extraction step to reduce the amounts of co-extracted fats, for the determination of pesticides in meat-based baby foods.

Thermo Fisher Scientific (San Jose, California) announced that it has been presented with the ACHEMA 2009 Innovation Award for the category of Laboratory and Analytical Techniques.

In this month's "GC Connections", John Hinshaw addresses the causes and effects of peak tailing, as well as ways in which chromatographers can measure and report their misshapen peaks.
