For alternative selectivity to traditional alkyl phases, we recommend you try the polar embedded phase BetaMax columns. The stationary phase contains urea groups embedded within the C12 chain, which extra interactions with samples to extend the capabilities of the phase.
BetaMax Acid is fully endcapped and based on a high surface area higly base deactivated 60Å pore size silica. The high surface area (540m2/g) gives the columns maximum retention, whilst the small pore size can also increase retention of small compounds that are able to fully access the pores. The high coverage C12 ligand gives the columns higher hydrophobic retention that other polar embedded phases, and compared to conventional phases (C18 or C8) it offers a completely new selectivity.
A polar functional group between alkyl ligands and the silica surface allows fast analysis without compromising the resolving power. BetaMax Acid is completely stable under 100% aqueous conditions, so it is ideal for 0 to 100% organic fast gradients or where a short column length is desired.
Other column dimensions and hardware designs are available. Please contact us for more information if you do not see the exact column that you are interested in.
