Effect of sample solvent composition when Asahipak
NH2P-50 is used is shown.
When making sample solution to be injected, sample should be
dissolved in a solvent whose composition is as close as the eluent,
preferably in the eluent. When 75% acetonitrile solvent is used for
the eluent and a sample cannot be dissolved in it, first, the sample
should be dissolved in a solvent which dissolves the sample, and then,
adjust the solvent composition to be acetonitrile aqueous solution of 50% or more.
