Partisil ODS3 is a C-18 polymeric phase with a 10.5% carbon load.
Partisil is a high-purity irregular silica gel available in both 5 and 10 µm particle sizes with a pore size of 80 Å. The choice of column packing includes Silica, C-18 polymeric phases (ODS-3,ODS-2) and C-8. Also available are SAX, SCX, and PAC. These columns provide reproducible results, column to column, lot to lot.
Partisil 10 µm analytical and semi-preparative HPLC columns are available in non-cartridge format only. Columns with a 4.6 mm Int.Ø use the WCS hardware. Columns with IDs of 9.4 or 20 mm use the Magnum 9 or Magnum 20 hardware respectively.
The medium of choice for improved speed, efficiency and resolution in applications requiring C-18 phases. End-capped for deactivation of silanols to minimize the need for ion suppression or ion pairing agents. Used in a wide range of applications with optimal selectivity, including pharmaceuticals, natural products, food, biological and environmental pollutants. Partisil ODS2 with a high carbon load (16%) makes this polymeric phase the most nonpolar and, therefore, the most retentive of the reversed phases. An alternative to end-capped C-18 where different elution order is desirable for optimum separation. High sample load capacity and 10 µm particle size are very suitable for preparative work. Partisil ODS is a C-18 phase with a 5% carbon load for both normal adsorption and reversed phase partitioning. Dual-mode operation for added selectivity with 50% residual silanols. Lightly loaded C-18 packing is particularly effective for compounds having greater water solubility when used in the reversed phase mode. Creates a moderately polar surface, different from that of pure silica, in normal phase mode.
