ACE Excel C4 UHPLC Column range is for RP Chromatography, offers high selectivity and Is less hydrophobic than C8 and C18 phases

According to the Hydrophobic Subtraction Model (HSM) of selectivity the colum has the following paramerters:

Manufacturer: ACT

Silica Type: B
H Parameter ( H parameter is a measure of the phase hydrophobicity) :0.670

S* Parameter (S* is a measure of the resistance of the stationary phase to penetration by a solute molecule) : -0.0100

A Parameter(A is a measure of the hydrogen-bond acidity of the phase) : -0.170

B Parameter ( B is a measure of the hydrogen-bond basicity of the phase): 0.0200

C Parameter (pH 2.8) (C is a measure of the interaction of the phase with ionized solute molecules) : 0.0900

C Parameter (pH 7.0) : 0.310

USP Type: L26
