LC Troubleshooting: How Much Retention Time Variation is Normal?
Small changes in retention time of a liquid chromatography (LC) method are normal. At what point is a problem suggested? Retention time shifts can be frustrating when you can't figure out if a shift is something you caused or if there is another reason for it. John Dolan explains more. More... |
Expanding the Understanding of Mineral Oil Analysis
The Column spoke to Laura Barp of the University of Udine about her research into mineral oil migration in food packaging, the potential impact on human health, and the importance of pressurized-liquid extraction (PLE) in this project. More... |
Tips & Tricks: How to Test GPC/SEC Columns
Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) columns are at the heart of a GPC/SEC system. Even when advanced detection, such as on-line light scattering, viscometry, or mass spectrometry (MS), is applied the quality of the results strongly depends on the least expensive part of the system, the separation columns. 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. More... |
