Chromegabond WR (Wide Range) is specially deactivated to produce superior peak shapes for amines and acids. Chromegabond WR superior performance is the result of a multistep process beginning with ultra pure synthetically produced spherical silica. This synthetic silica is manufactured using ultra pure metal free reagents. The resultant particles are carefully analyzed to ensure that their metal-free properties are completely maintained. The ultra-pure silica particles are then fully hydroxylated before they undergo an extensive bonding of either monomeric C4, C8 or C18 alkyl chains, using our proprietary bonding procedures. The bonded particles are then exhaustively endcapped to react any remaining silanol groups. Our proprietary endcapping reagents and procedures yield columns that are much more resistant to degradation by acidic and basic mobile phase compositions, while improving peak shapes for amines and acids.
