Is 100% aqueous stability and unique polar selectivity not enough to convince you to try Luna Omega? Well, here is another equally-compelling reason Guest Author: Dr. Jeff Layne You Can Never Have Too Much Efficiency! The efficiency of a column is a measurement of the amount of band broadening that 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.
Last month, Phenomenex hosted the SoCal Dietary Supplements Chromatography Forum—an all-day assembly co-sponsored by Alkemist Laboratories and US Pharmacopeia (USP) to discuss “the need and approach to modernizing USP dietary supplement monographs,” particularly those based upon chromatography.
There are several critical characteristics to take into consideration when choosing the appropriate organic solvent to use in liquid chromatography. For example, high viscosity solvents may produce backpressures that are too high for the HPLC system used.
Whether it be for a job interview or medical diagnosis, most of us have found ourselves in the vulnerable position of peeing into a cup. And though it may feel invasive or embarrassing, urine tests are remarkably helpful to doctors, courts, and hiring managers alike.
Hydrophilic interaction liquid chromatography (HILIC) is a chromatographic mode used mainly for the separation of polar compounds that are too hydrophilic to be retained in a reversed phase column.

In the spirit of frugality, process chromatographers often want to save and store their media for future use. There are steps one can take to store bulk resins for short term and long term use, though it’s worth noting that the media will not last forever.
Many pet owners can tell if their furry friend is sick just by looking at them. What if there was a possible diagnosis lurking in your cat’s litter?
