Sample Preparation

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

Analysis by mass spectrometry (MS) of integral membrane proteins and those associated with membrane is an important aspect of proteomics.

This month's installment of "Sample Prep Perspectives" describes a new extraction technique called QuEChERS (standing for quick, easy, cheap, effective, and safe and is pronounced "catchers") for the sample preparation of pesticides in foods and agricultural samples.

This month's installment of "Column Watch" is the conclusion of a two-part series in which columnist Ron Majors examines trends in column and sample prep introductions at Pittcon 2007.

Modern Liquid Chromatography was the hot topic of the day in a standing room only technical session on the third day of Pittcon 2007. Arranged by Peter W Carr (University of Minnesota) and Stephen G Weber (University of Pittsburgh), the session's favorite subject seemed to be high performance liquid chromatography (HPLC).

For a young scientist, being recognized for your hard work at such an early stage in your career is a tremendous honor.

A topic on everyone's minds these days, especially those of us who traveled by air to get to Pittcon, is Homeland Security.

The Ancient Greeks ate sheep testicles before competitions. Contemporary athletes have designer steroids. What techniques can we use to test our athletes for banned substances?

Yesterday, Andrew Tiplerwas going nowhere fast because of airport delays. Today, he was discussing how to accelerate your gas chromatography runs.

Shana Kelley received the Pittsburgh Conference Achievement Award in a ceremony on Monday morning of Pittcon 2007.

Eight presentations on a variety of LC-MS applications were given in Session 170 on this first afternoon at Pittcon. One of the most interesting was session 170-6, "Techniques of LC-MS in Forensics Analysis." The speaker, Michael C. Zumwalt, discussed the variety of LC-MS instrumentation available to meet both qualitative and quantitative needs. Among the interesting applications he discussed were those for detecting drugs of abuse and explosives. Workplace drug testing and forensic toxicology are examples of these applications. LC-MS continues to be a rapidly growing technique, and the ways in which it can be used in forensic analysis are quite varied. Serial measurement systems are used for quantitation, while parallel systems are best for qualitative applications. Serial systems such as single quadrupole and triple quadrupole mass spectrometers are very useful for detecting drugs of abuse in oral fluids. A particular advantage noted by the speaker is the ease of sample collection, which can even be done in the field, for example, by a police officer.

Most arrived at Pittcon 2007 wet, cold, and frustrated. But a the blizzard whooping around Chicago couldn't bring David Schwartz down today when he was presented with the 2007 Pittcon Heritage Award.

As most of us traveled by air to Chicago this weekend, we all passed through airport security and the various drills like taking off our shoes, removing metal objects and taking the all-important laptop out of its case.

Sunday afternoon's plenary lecture at Pittcon 2007 was given by Charles M. Lieber and was titled "Nanowire Nanoelectric Devices for Detection of and Interfacing to Biological Systems."

Pittcon 2007 opened with a bang here in Chicago, albeit a snowy bang. All the liquid falling outside, whether in rain, snow, or ice form, was nothing compared to the liquid chromatography sessions.

Good morning, and welcome to the opening day of LCGC's "Meeting Report" from Pittcon 2007 in Chicago, Illinois.

Separation instrument techniques are among the most widely used technologies in the analytical instrumentation market. It spans the entire industrial and regional marketplace. The lab separations market includes chromatographic techniques like analytical and preparative HPLC, GC, IC, TLC, flash, and low pressure LC.

Each month in our Technology Forum we will feature a discussion between industry experts on various trends and issues in the chromatography field. This month's Technology Forum looks at the topic of Pittcon 2007 and the trends and issues surrounding it. Joining us for this discussion are Tom Ricci with Ricci Communications and LCGC Columnists John Dolan and John Hinshaw.

According to "Column Watch" Editor Ron Majors, Type C silica is a term introduced by Dr. Joseph Pesek of San Jose State University (California).
