The Shodex™ guard column for preparative size reversed phase polymer ODP-50 10E and ODP-90 20F. The guard column protects against non-specific binding and physical fouling of the frits and solid support. Thus, the life of the preparative column is extended.
The relatively large pore size of these columns are suitable for the purification of amino acids, peptides, and proteins. Moreover, the rugged solid support is usable in a wide pH range from pH 2 to 13. Usable in 100 % water and buffer solution. Best used for the purification of basic substances.
