Japan YMC-Pack C4 Series HPLC Columns

High coverage completely bonded spherical silica support fully capped particle size range, with the 50μ from analysis of 3μ to preparation. Effective pore size of 12nm (120A), 200A, 300A. YMC-Pack C4 fast the separation of mixed polarity samples. YMC-Pack C4 (butyl) and C8, C18 compared to less hydrophobic, water phase ingredients typically used in high eluate. When using the same eluent, compared to C8 and C18, for non-polar compounds exhibit a shorter retention time, no significant effect on polar compounds. In addition a wide range of polar component mixture analysis preferably YMC- Pack C4. This is due to the butyl bonded phase gives a relatively short analysis time and very high resolution.

Samples produced is pure high concentration of high biological activity.
