The intensity of the light scattering signal depends on concentration, molar mass, and the specific refractive index increment, dn/dc, of the sample. dn/dc therefore usually needs to be known to derive molar masses by gel permeation chromatography/size-exclusion chromatography-light scattering (GPC/SEC-LS). How to overcome the issue of unknown refractive index increments is outlined in this instalment of Tips & Tricks. In particular, a new approach to derive molar masses by GPC/SEC-LS that requires only the molar mass of a reference material, and not the dn/dc of the sample or of the reference material, is introduced.

A preview of HTC-15, which will be held at Cardiff City Hall, Cardiff, United Kingdom, from 24–26 January 2018.

The three-day Chromatographic Society meeting was held on Monday 15th until Wednesday 17th May 2017 and was hosted by Pfizer at Discovery Park in Sandwich, Kent, UK. This comprehensive symposium featured oral presentations from leading practitioners of supercritical fluid chromatography (SFC) and ultrahigh-pressure liquid chromatography (UHPLC) from across Europe. Some of the latest innovations and applications were described and the lectures were augmented and supported by a comprehensive exhibition of instrumentation and consumables. The attendees gained insight into practical application of these techniques across a variety of industries, particularly the pharmaceutical industry. The comprehensive programme had a significant focus on SFC for chiral and preparative-scale analysis.

To resolve and quantitate monoclonal antibodies and antibody–drug conjugates, analytical scientists need various chromatographic modes, such as sizeexclusion, ion-exchange, hydrophobic interaction, and hydrophilic interaction chromatography. Here, we provide advice for making the most of each mode.

Systematic toxicological analysis is an important step in medicolegal investigations of death, poisoning, and drug use. The primary goal is the detection and confirmation of potentially toxic compounds in evidence. This article describes a workflow using nontargeted liquid chromatography–tandem mass spectrometry (LC–MS/MS) for reliable compound identification.

In his final column before retirement, John Dolan reminisces about his years as the author of “LC Troubleshooting”, and some of the changes that have taken place in liquid chromatography (LC) technology during that time.

Separating proteins and antibodies is a unique analytical challenge because of the complexity of the analytes. Both sample heterogeneity, because of a number of chemical modifications to the analyte, and nonspecific binding to the silica surface often result in chromatographic peak broadening and tailing. This instalment of “Column Watch” focuses on several different chromatographic strategies that analytical scientists can use to resolve and quantitate various biomacromolecules, including monoclobal antibodies (mAbs) and antibody–drug conjugates (ADCs). Selected aspects of size-exclusion, hydrophobic interaction, ion-exchange, hydrophilic interaction, and reversed-phase chromatography are discussed.
