In two new videos from LCGC TV, Milton L. Lee from Brigham Young University discusses the principles of TGGC, and the possible advantages of TGGC over traditional GC methods.

Scientists from Bristol-Myers Squibb Company have developed a novel approach for the simultaneous quantitation of neutralizing antibodies, residual drug, and human Immunoglobulin G (IgG) in immunogenicity assay development using liquid chromatography?tandem mass spectrometry (LC–MS–MS). This work published in Analytical Chemistry presents a new approach that aids the refinement of therapeutic protein neutralizing antibody assays in drug development.

Chromatography has taken a prominent place in the characterization and analysis of protein therapeutic drugs and today it plays a critical role in the biotechnology laboratory.

Gerard Rozing has been announced as the winner of the second annual Uwe D. Neue Award in Separation Science.

An examination of the development of new types of columns based on different particle types, sizes, and other physical characteristics and how they can improve the speed and efficiency of HPLC used to support more expansive and complicated analyses

The winners of LCGC's seventh annual awards are highlighted.

New product introductions in the areas of HPLC columns for reversed-phase LC, HILIC, ion-exchange and ion chromatography, SEC, and specialty columns for specific types of analyses are covered.

A brief introduction to the articles presented in this supplement

Why do core–shell particles provide an increase in efficiency?

Size-exclusion chromatography is an important technique in biopharmaceutical characterization. This article discusses its use for soluble aggregation analysis and quantitation.

Some attributes of large molecules make them behave differently from small molecules in reversed-phase separations.

The variation in selectivity of aromatic hydrocarbons with bisubstituted polar groups is investigated in systems consisting of C18 stationary phase and ternary eluents. The solutions of the ternary eluents were obtained by mixing binary solvents (organic modifier + water) of similar eluent strength. Acetonitrile, methanol and tetrahydrofuran were the organic modifiers applied. The influence of the organic solvent type and its concentration in the ternary mobile phase on retention and selectivity of the solutes is discussed. An approach previously presented by our group was adapted to explain the selectivity changes.

Part 1 of our annual report on new products introduced at Pittcon. This month, columns are highlighted, covering HPLC/UHPLC columns, packings, and related products.
