    Specifications :
․Phases: C18
․Particle Sizes: 4.5μm
․Pore Size 100Å
․Pore Volume 1.1mL/gm
․Surface Area 430m2/gm
․%Carbon (w/w) C18 = 18%

    Features :
• Monofunctional & fully endcapped
• Ultra High Density End Capping
• Ideal for Basic and Acidic Analytes
• Wide pH Range Stability: The unique endcapping reduces acid/base hydrolysis of the 
   bonded phase and greatly reduces silica solvation at high pH
• High Capacity
• High surface area
• No secondary Si-OH interaction
• No metal contamination
• Extreme hydrophobicity range

＜2＞
    Specifications :
• Phases: C18
• Particle Sizes: 3 and 4.5 μm
• Pore Size: 120Å
• Pore Volume: 0.8mL/gm
• Surface Area: 330m2/gm
• Carbon%(w/w) C18 = 18%

    Features :
․Monofuctional with a unique polar and bulky end-capping
․Ideal for applications requiring an absence of secondary solute-silanol interaction
․Basic and acidic drugs and peptides can be chromatographed efficiently with little or no
    buffer
․Well suited for LC/MS applications where acetic acid or formic acid can be substituted f
    or TFA resulting in significant increase in signal
․Fast equilibration kinetics from high to low organic phase compositions
․Works well in 100% aqueous conditions for hydrophilic applications
