Improved Peak Shape with Prevail™ Amide
• Polar Embedded Group Improves Peak Shape of Polar Samples
• Packing Media Provides Unique Selectivity
• Bonded Phase does not Collapse Under 100% Aqueous Mobile Phase
A Polar Embedded Group inserted into the hydrophobic chain of the Prevail™ Amide phase
minimizes interaction of polar samples with silanols providing symmetrical peaks for a
wide variety of applications. The spatial location of the polar amide group within the
reversed phase chain allows it to strongly interact with silanols so that your basic samples
do not. The presence of the amide group alters the selectivity of the reversed-phase packing
allowing separations often hard to achieve on conventional reversed-phase columns.
Most C18 phases are not wettable with 100% aqueous mobile phases and collapse
when challenged with an all-aqueous solvent. The amide group keeps the bonded phase
from collapsing under 100% aqueous conditions, even at pH 1.0, allowing the analyst to
use these mobile phases to more fully resolve polar analytes. Additionally this material
excels under a full spectrum of conditions including up to 100% organic mobile phase.
