The answer to the following question was provided by LCGC's "LC Troubleshooting" columnist John Dolan. Q: Since acetonitrile is in short supply and the prices have sky-rocketed in recent months, what can be done about replacing this solvent with others for various chromatography applications?

FMS introduces the first and only "Total Solution" Sample Prep system available that combines three sample prep processes into one economical package. The Total-Rapid-Prep performs the extraction, sample clean-up and concentration for six samples simultaneously in less than a few hours, producing the highest recoveries and best results for all analytes.

Streptomycin and neomycin are members of the family of antibiotics called aminoglycosides. Aminoglycoside antibiotics are complex organic molecules produced by streptomyces strains and are extremely important in clinical medicine, due to their efficacy and low cost.

A miniature gas chromatograph is described having the following key features: a miniaturized chemical trap for enrichment, rapid thermal desorption of the trap, a resistively heated capillary column for programmed GC analysis, and a micro-chip based plasma emission detector (PED).

What measurements are required for system suitability?

2009 Emerging Leader Winner

Columnist Ron Majors discusses some of the practical considerations in the successful application of the popular yet age-old technique of solvent extraction (also known as liquid–liquid extraction, or LLE). After a brief review of the basics, guidelines on the selection of the appropriate extraction solvents and how to use acid–base equilibria to ensure efficient extractions of ionic and ionizable compounds are provided. Problems in LLE and the solutions to these problems are highlighted. A newer technique called dispersive liquid–liquid microextraction (DLLME) is introduced.

Pittcon celebrates 60 years of service to the scientific community and remains an unmissable event in the analytical chemistry calendar.

2009 Lifetime Achievement Winner

A review of the role of Solid-phase Microextraction (SPME) in quality control (QC) in the fish oil industry.

A miniature gas chromatograph incorporating a miniaturized chemical trap for enrichment, rapid thermal desorption of the trap, a resistively heated capillary column for programmed GC analysis and a micro-chip-based plasma emission detector (PED) is described. The sampling and chromatographic conditions for the analysis of volatile compounds in air are presented. The performance of the µCAD is illustrated in the universal (carbon) mode and for the selective detection of chlorinated and organo-mercury compounds. Detection limits (DLs) are at the sub-μg/L level in the carbon mode and 10 ng/L for organo-mercury compounds.
