WebHere are seven key traits to consider: 1. Particle shape The shape of silica particles can have a significant impact on separation efficiency. Spherical particle shapes result in more homogenous packing characteristics than irregular shapes. Spherical silicas are more resolutive, and peaks are farther apart from each other. WebHis GraviTrap™ columns are designed for fast and simple puriﬁcation of histidine-tagged proteins using gravity ﬂow. Both clariﬁed and unclariﬁed sample can be applied to the column. The column is prepacked with Ni Sepharose ® 6 Fast Flow.

"WebChromatography systems are often defined by their pressure characteristics. Common acronyms like LP or HPLC are used to refer to low-pressure and high-pressure liquid chromatography, respectively. Systems that operate at pressures <50 psi (~3 bar) are categorized as low-pressure chromatography systems. " - Gravity chromatography
