Reliable Reproducibility and More Selectivity from Superficially Porous Particles 

Superficially porous particle technology is no longer new. There are many more options available now, and new phases are often released. These columns are being adopted by more chromatographers every day as a way to save time and increase lab throughput. Nonetheless, many chromatographers are still using conventional 3.5µm and 5µm columns when they could be seeing significant time savings and improved resolution from superficially porous technology. In this article Agilent Poroshell 120 columns were used to illustrate some of the benefits that superficially porous particles provide.
