Capcell Pak C18 ACR | HPLC Column | Particle Size 3μm

Capcell Pak C18 ACR (ACR stands for Acidic Resistance) has the highest level of acid resistance in the lineup of columns offered by Osaka Soda. This HPLC column has high selectivity for planar structure compounds and polymeric separation characteristics. It is suitable for continuous use in the low pH range and analysis of structural isomers.  This packing material realizes not only basic resistance but also outstanding acidic resistance generated by further improvements to the polymer coating technology used for CAPCELL PAK. This column can be used under strongly acidic conditions (pH 1 to 2) and low organic contents. Features Top acidic resistance Proved by a unique severe acid resistance test (pH 1). Optimum for peptide mapping where TFA and formic acid are frequently used HPLC Conditions Mobile Phase: (A) 2 vol% TFA in H2O (pH = 1)(B) 2 vol% TFA in acetonitrileB solution: 65% (20 min) → 0% (60 min) → 90% (5 min) → 65% (5 min) Temperature: 60°C Flow Rate: 1.0mL/min Detection: UV 254nm Samples: Uracil and amylbenzene Minimal residual silanol groups Polymer coating technology minimizes hydrogen bonding, which is a parameter reflecting the influence of residual silanol groups Free from tailing Sharp peak shapes achieved by strictly controlled polymer coating Full range of column sizes A complete lineup from microcolumns of 0.3 mm i.d. to LC-MS fast columns 20 mm long and semi-preparative columns Pore size(nm) Particle size(µm) Specific surface area(m 2/g) C% Density(µmol/m 2) Functional group Acceptable pH USP 8 5 300 17 2.6 Octadecyl group 1~10 L1 8 3 300 17 2.6 Octadecyl group 1~10 L1   Application Data   Capcell Pak C18 ACR Application Library
