The rise of 2D LC

This feature discusses the rise of two‑dimensional liquid chromatography (2D LC) and its potential for routine analysis.

CF3 for characterizing nanoparticles

Centrifugal field-flow fractionation (CF3) can be performed to separate nanoparticle mixtures based on size, aspect ratio, and density, with high reproducibility and resolution. This article explains more.

FFF of biomolecules and nanoparticles

The different types of field-flow fractionation (FFF) methods that have been developed to determine the mass, size, and composition of biomolecules and nanoparticles are discussed. There is also a focus on characterization by light scattering and inductively-coupled plasma mass spectrometry (ICP–MS).

Tips and tricks for testing GPC/SEC columns

Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) columns are at the heart of a GPC/SEC system. An easy test to determine the plate count, the peak symmetry, and the resolution of the columns is therefore an essential tool to ensure GPC/SEC system functionality.

The 5th ICPC conference: A preview

The 5th International Conference on Polyolefin Characterization (ICPC) will be held at The Westin Valencia Hotel in Valencia, Spain, from 21–24 September 2014.
