Use of C18 Silica Cartridges to Purify and Characterize Pterins

摘要

The C18 silica cartridge is shown to be useful to prepare samples for quantitative analysis. The concentration of the compound to be analyzed and the removal of some interfering substances can be accomplished simultaneously. The purpose of this report is to describe the basic principles that govern adsorption of pteridines to C18 silica cartridges. 5 refs., 1 fig., 1 tab. (ERA citation 11:005566)
