Rapid analysis of polycyclic aromatic hydrocarbons
June 4th 2010A rapid gradient HPLC method for simultaneous determination of 16 PAH according to EPA 610 method is presented. A baseline resolution for all 16 target analytes in less than 2.50 minutes could be achieved by using a KNAUER BlueOrchid PAH 50 x 2 mm column.
Matrix Elimination — In-line Removal of Chloride using InGuard Ag and Na Cartridges
June 1st 2010In ion chromatography, the presence of a large amount of matrix ions makes quantification of the target ions difficult. Selective removal of matrix ions - matrix elimination - can be performed by treating a sample with a solid-phase extractant. Halides can be removed by precipitation with silver, which is present as a counterion in a cation-exchange resin. A subsequent treatment with a cation-trapping column removes residual dissolved silver ions.
Planning a Busy Summer at LCGC
June 1st 2010Traditionally, summer is a time when the worlds of lab research and business slow down to a large extent. If you work in academia, chances are many of your students have returned home for the summer and the teaching load has been reduce, while those of you working in private industry and research labs may see coworkers taking long-anticipated (and well-deserved) vacations.
