Alternative Selectivity to C18 Columns

COSMOSIL PFP provides different selectivity from C18 Columns. Furthermore it offers improved separation compared to other companies' PFP columns.

Column size: 4.6 mmI.D. x 150 mm
Mobile phase: Methanol : Water = 40 : 60
Flow rate: 1.0 ml/min
Temperature: 30°C
Detection: UV 254 nm
Sample: 1. o-Cresol (3.0 mg/ml)
2. m-Cresol (3.0 mg/ml)
3. p-Cresol (3.0 mg/ml)
Injection vol.: 1.0 µl

Separation Properties of PFP

COSMOSIL PFP uses dipole-dipole and π-πinteractions. It offers strong retention for compounds with strong dipole moments, e.g. cationic or halogenated compounds. It also has high steric selectivity for structural isomer separations.

Column size: 4.6 mmI.D. x 150 mm
Mobile phase: Methanol : Water = 50 : 50
Flow rate: 1.0 ml/min
Temperature: 30°C
Detection: UV 254 nm
Sample: o-Dinitrobenzene
m-Dinitrobenzene
p-Dinitrobenzene
Benzene (I.S.)
