Torrance, Calif. -- Phenomenex Inc., global leader in the research, design and manufacture of advanced technologies for the separation sciences, is introducing two new offerings to its Luna Omega fully porous LC column line – the Luna Omega 3 µm Polar C18 and the Luna Omega 3 µm PS C18.

The Luna Omega Polar C18 stationary phase is a unique, robust selectivity bonded to an innovative silica particle that delivers high loadability and retention for both polar and nonpolar analytes. This new phase is 100 percent aqueous-stable due to a polar-modified surface, providing flexibility in solvent and gradient system selection needed to achieve desired polar/nonpolar analyte separation. The new 3 µm particle joins the existing 1.6 µm and 5 µm sizes to provide full scalability from UHPLC to HPLC to preparative chromatography.

Unlike a traditional C18, the Luna Omega PS C18 delivers two distinct and useful separation mechanisms and offers 100 percent aqueous stability. The particle surface of the PS C18 contains a positive charge that facilitates greater acidic compound retention through ionic interaction, while the C18 ligand delivers general reversed-phase retention. This mixed-mode selectivity is a valuable tool for greater separation between mixtures of compounds that have varying functional groups, such as peptides, pesticides or metabolite profiles. Additionally, the positive surface charge encourages sharp basic compound peak shape through the ionic repulsion of these compound species. Like the Luna Omega Polar C18, the three PS 18 particle size choices enable full scalability from…

    On the final day of July, 2016, I was working on a forest inventory near the town of New Meadows, Idaho. I had just moved my truck to a new location, and was still sitting in the cab, when I saw motion a short distance away. A badger had emerged from its burrow, and was busy digging the loose soil. My camera was conveniently located on the passenger seat. I raised the camera and quickly snapped a picture, figuring that the badger would see me and quickly scurry away. My first…
