The Acid Test —More Useful Calculations for HPLC Eluent Preparation
Mobile-phase preparation for LC–MS requires careful consideration to ensure the correct pH values and concentrations are obtained. This blog installment details the difference between using volume percent and weight percent to make up 0.1% solutions of trifluoroacetic acid and the effect it has on the pH. |

Separation Science in Drug Development, Part II: High-Throughput Characterization
This installment provides an overview of high-throughput characterization techniques of drug leads to support small molecule drug discovery programs in a pharmaceutical company. A myriad of analytical chemistry techniques including separation science methodologies are used to confirm the structures and identities, quantitating the concentrations of stock solutions, and measuring key physicochemical properties of the new chemical entities (NCE). A case study is used here to illustrate the details of these applications in high-throughput characterization.

Living Off the Fat of the Land: Lipid Extraction Methods
Recently, Nature and Science Citation Index listed the 100 most cited research papers of all time. Two of these are the classic Bligh-Dyer and Folch lipid extraction methods from the late 1950s. Here, we look at the lasting impact of these papers and explore the current state of lipid extractions, including lipidomics.
