Valentina D’Atri from the University of Geneva spoke to The Column about the evolving role of HILIC in biopharmaceutical analysis.
Features
Combinations of detectors are often used in gel permeation chromatography/size-exclusion chromatography (GPC/SEC) to measure absolute molar masses or chemical compositions as a function of elution volume. Such multidetector setups require the correction of the delay volume between the detectors for correct data processing. This instalment of Tips & Tricks explains more.
Do you understand the benefits of selectivity as a method development opportunity?
Flow-field flow fractionation (flow-FFF) offers highly versatile separations for the analysis of complex fluids, covering a size range of macromolecules and particles from 1 nm to 10,000 nm. However, flow-FFF is often perceived as a difficult technique to learn because of the multiple parameters available for adjustment. Recent advances in software for simulating flow-FFF overcome this obstacle, enabling the virtual optimization of flow-FFF methods and opening up the power of flow-FFF separations to non-experts. An added benefit is the ability to easily analyze particle size distributions by elution time from first principles.
The Royal Society of Chemistry’s Environmental Chemistry Group, Water Science Forum, and the Separation Science Group Joint Meeting was held on Friday 3 March 2017 at the Science Suite of the Royal Society of Chemistry, in Burlington House, Piccadilly, London, UK.
