A group of researchers has studied the migration of monomers and plastic additives from plastic food packaging in microwave heated homemade food and packed liquid food using QuEChERS and gas chromatography coupled to mass spectrometry.
Researchers from the China Pharmaceutical University in Nanjing, China, have published a review of the recent advances in the preparation and application of monolithic capillary columns in separation science.
Victor U. Weiss and Günter Allmaier from TU Vien discuss how combining molecular beacons with chip capillary electrophoresis (CE) offers scope to investigate viral RNA replication and improve gene therapy delivery systems.
Doping and cheating the competition may be as old as competition itself. Doping horses for chariot racing was reported during the Roman Empire and doping is now commonly reported in the press. Advanced technologies such as ultrahigh-pressure liquid chromatography (UHPLC) analysis coupled to ultrafast tandem mass spectrometry (MS/MS) detection provide excellent sensitivity for the analysis of horse doping agents.
This instalment of Tips & Tricks shows the influence of analytical parameters on gel permeation chromatography/size-exclusion chromatography (GPC/SEC)–light scattering results when artificially wrong parameters reflecting typical experimental errors are used.
