YMC-Pack Pro C4, Capillary Guard Column 1/32", 12nm, 5µm, 5 x 300µm

With Pro C4, YMC offers a stationary phase based on the well-known ultra pure silica of the ProFamily. Compared to a C18 phase with the same eluent, C4 phases are less hydrophobic and gives shorter retention times for non-polar compounds while the retention time of polar analytes are virtually unaffected. This makes the Pro C4 an interesting alternative especially when short analysis times are required.

• Proprietary endcapping in order to minimize the effect of residual silanols
• For polar orgaic molecules, especially basic pharmaceuticals and peptides
• Ideal for fast chromatography
