The Essential Guide to: Understanding Stationary Phase Chemistry for Reversed Phase HPLC (Part I)

High content screening (HCS) is a high-throughput method, which enables the functional analysis of cells.

What is the best way to regenerate a polymeric column?

GPC/SEC analysis reveals a multitude of molar mass information about unknown samples that are chemically simple or homogenous.

Chiral has long been one of the most important techniques in separation science. Joining us for this discussion are Martin Vollmer of Agilent Technologies and Elena Eksteen of Chiral Technologies.

LCGC reviews some of the highlights and award recipients from this year's ASMS conference, held May 23-27, 2010, in Salt Lake City, Utah.

Agilent Technologies and Stemina Biomarker Discovery have announced that Agilent will be providing a liquid chromatography system and quadrupole time-of-flight mass spectrometer to accelerate Stemina's metobolomic research.

Polysaccharide-based chiral stationary phases (CSP) are widely used due to their wide chiral recognition ability. Several cellulose and amylose derivatives are extremely effective in the separation of a wide range of compounds of interest in the pharmaceutical industry (1).

A 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.

India?s National Institute of Nutrition, located in Hyderabad, India, has purchased eight rapid separation liquid chromatography systems from Dionex.

Shimadzu?s brand-new GCMS-QP2010 Ultra delivers unsurpassed scan speeds.

Ten miles off the Californian coastline, at the bottom of the Santa Barbara channel, domes rise from the Pacific Ocean floor. A paper published on-line in the journal Nature Geoscience identified these as a series of unusual underwater volcanoes.

In 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.

Traditionally, 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.
