Offering expanded pH range capability (0-14), elevated temperature ranges, increased longevity and novel selectivity, without compromising efficiency.
SCX HPLC columns are made of spherical silica particles of the highest purity (>99.999%), and bonded with an aromatic sulfuric acid group. They can be used to separate basic, water-soluble compounds and bio-molecules.
Ascentis® Express provides the high speed and high efficiency of sub-2 μm particles, but at approximately half the backpressure for the same column length. This lower pressure means that Ascentis Express can be run on conventional HPLC and LC-MS systems, as well as mid-pressure or ultra-high pressure (UHPLC) systems. Lower pressure also means ...
This is the original Luna C18 and can be used when maximum retention of non polars is desired.
Octadecyl silane ligands are bound to the silica surface, making for a very hydrophobic phase with great methylene selectivity.
5-carbon chain ligands are bound to the silica surface offering a lesser degree of hydrophobic selectivity compared to C8 phase columns.
Octyl silane groups bound to the silica surface with non-polar end capping offer moderate hydrophobic selectivity and virtually eliminate silanol interactions.
Nitrile groups bound to the silica surface offer a unique polar selectivity under reversed phase or normal phased conditions.
Amino groups bound to the silica surface serve as a weak anion exchanger and offer polar selectivity under reversed phase and normal phase conditions.
