A research group from Kangwon National University (South Korea) set up a laboratory-scale test cooling bench with an airflow, temperature, and relative humidity controller and used it to simulate the unpleasant odor produced by an automobile air conditioner evaporator.

Polymer Laboratories, now a part of Varian, Inc., has published an application note on Universal quantification using ELS detection and real-time response control. The ability of the Varian 385-LC to overcome solvent enhancement effects during gradient elution makes it ideal for quantifying unknown compounds. This application note shows that combined with the improved sensitivity to semi-volatile compounds at sub-ambient temperature, the Varian ELSD offers a simple and accurate solution to universal quantification.

Q&Q The Column's Alasdair Matheson spoke to Rohan Thakur from thermo Fisher Scientific about the company's rationale behind developing the TSQ Vantage — a triple quadrupole mass spectrometer — for high sensitivity bioanalysis.

Micellar liquid chromatography (MLC) is a reversed-phase liquid chromatographic mode with a solution of surfactant forming micelles as the mobile phase. The interaction of solutes with the stationary phase coated with surfactant monomers, combined with the increased solubilization capability of micelles, have profound implications with regard to retention, selectivity and efficiency. Practical steps that a chromatographer involved in MLC should consider when developing an analytical procedure are described, including mobile phase preparation, column conditioning and cleaning.

Agilent Technologies (Santa Clara, California) and the University of Technology Sydney (UTS, Sydney, Australia) have established the UTS Elemental Bio-Imaging Facility to study trace metals and other elements in tissue and their effects on health.

They say that timing is everything, and though this saying may have originally been applied to Broadway and Vaudeville in the early twentieth century, it is just as true when it comes to the field of modern-day separation science. For this September issue of The Application Notebook should be reaching our audience of analytical chemists, lab managers, and other industry professionals just as the busiest time of the year ramps up in the world of chromatography.
