Gas Chromatography (GC)

Shimadzu Scientific Instruments (Columbia, Maryland) updated its existing System GC Program to include the GC-2014 gas chromatograph. In addition, the program now offers new streamlined systems for natural gas, transformer gas, and greenhouse gas analysis, as well as biofuels and biomass feedstock research.

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.

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.
