Asahipak ODP-50 (C8P, C4P series) Manual popular "C8" or "octyl" columns. Thus Asahipak columns for reversed phase chromatography combine a range of hydrophobic character commonly found in silica packings with the high chemical and physical stability of polymer based particles. The user should read this entire manual before using the column, especially for the first time.

Asahipak ODP-50 (C8P, C4P series) Manual 4. Column installation 4.1 Direction of flow Install and use the column with mobile phase flowing in the direction indicated on the column tag. If the column shows very high resistance to flow, it may be partially plugged up. This is probably the end of the service life of the column.

Asahipak ODP-50 (C8P, C4P series) Manual 4.5 Connection of column to HPLC Connect the column inlet to the tube from the injector. Do not turn the fitting tight. Turn on the pump flow to one half the lower operating range in Table 1. Allow a small amount of the mobile phase to leak out and displace any air bubbles from the cavities in the column inlet.

Asahipak ODP-50 (C8P, C4P series) Manual For control of pH within the range of pH 2 to pH 13, phosphate, acetate, tris-HCl, NaCl, KCl, , and trifluoroacetic acid buffers can be used. Please consult your Asahipak representative if you have questions about buffering agents not listed above. It is important to note that the mobile phase should be filtered before use as described in section 5.1.

Asahipak ODP-50 (C8P, C4P series) Manual could precipitate during standing or by adding the 50% methanol, see Section 6. Also it is important that the column not be permitted to dry out. 11. Sample preparation In general, the sample should be dissolved in the mobile phase. Dissolving the sample in the mobile phase often avoids large "system peaks"...
