Gel permeation/size-exclusion chromatography (GPC/SEC) is the standard method for separating samples by molecular size and determining molar mass distributions. However, GPC/SEC instruments can also be used to investigate porous materials and to learn more about pore size distributions, as a powerful alternative to nitrogen gas (N2) adsorption or mercury (Hg) intrusion porosimetry.

Researchers from Imperial College London and the University of Aberdeen have identified disease markers for Human African Trypanosomiasis (HAT), commonly known as “sleeping sickness”. Using reversed-phase ultrahigh‑performance liquid chromatography coupled to mass spectrometry (UHPLC–MS) and proton nuclear magnetic resonance (1H NMR) spectroscopy researchers found 53 discriminatory metabolite markers.
