Sigma-Aldrich places “global-citizenship” at the heart of its business.

Using spectroscopy to protect and improve the quality of life for people worldwide.

Lawrence (Larry) Lesko is a bioanalytical veteran with many years of academic and FDA experience. Now, as director of the University of Florida’s Center for Pharmacometrics and Systems Pharmacology, Larry uses metabolomics to discover biomarkers of drug toxicity.

This paper shows how using a solvent trap can be used to prevent sample drying/solvent loss during extended testing, helping to ensure that only rheological changes are being measured and not artifacts resulting from drying of the sample at the air/sample interface.

The top 10 reasons to consider an advanced multi-detector SEC system, which incorporates light scattering detectors for the measurement of absolute molecular weight and molecular weight distribution with excellent accuracy.

The stability of a protein sample and its tendency to aggregate is explored using a combination of SEC-MALS and DLS

Read how DLS-based optical microrheology can be used to determine the rheological behavior of polymer solutions and the impact of tracer particle chemistry on the measured microrheological response.

Monika Dittman (Agilent Technologies) and Fabrice Gritti (Waters) offer a manufacturer point of view on the practical limits of LC.

The evidence contradicts those who say liquid chromatography has fully matured.
