When performing reversed phase LC separations, there is a natural tendency of method developers to reach for the most commonly used phase—a C18. However, there are so many different variations of C18 phases available to method developers that it often becomes difficult to choose a C18 column that one had Continue Reading
Guest Author: Technical Specialist, Ann Montross Silica media in HPLC columns were originally irregular shaped particles of silica. Then silica based HPLC columns moved to the traditionally filled, fully porous spherical particles of silica that offered improvements in chromatography over irregular shaped particles. Figure 1: Fully Porous Particles As the Continue Reading

You’ve worked so hard crafting the perfect costume, decorating your home, and sneaking chocolate from your kids, we decided to treat you to the best technical guides this Halloween.
Peak shape issues at the apex of a peak are typically related to detector saturation. This symptom can be observed as flattening and/or noise at the peak apex.
Valentine’s Day is approaching, love is in the air, and recent freezing temperatures make for perfect cuddling conditions. How appropriate, then, that today—January 21—is National Hugging Day!
