SiELC Newcrom BH HPLC Columns

SiELC Newcrom BH is a mixed-mode HPLC column with positively charged basic ion-pairing groups at the terminal end of short ligand chains. This new generation of mixed-mode column moves the charged embedded functional group away from the silica surface enabling uniform surface charge density. Limitations such as restricted use of methanol in the mobile phase, poor peak shape, low efficiency of multi-charged molecules, high buffer concentration requirement and poor retention of non-charged molecules have been overcome with the Newcrom stationary phases.

Newcrom BH is based on spherical silica particles with 100 Å pores and particle sizes of 3 µm and 5 µm. It has a longer ligand chain (25 Å) compared to Newcrom B (100 Å). The longer ligand chains reduce the number of ionic groups over any given surface area, so Newcrom BH has an increased ion capacity compared to Newcrom B.
