Generic Gradients for Fast Separations

For components to be isolated in the mg to g range, tedious method development is not advisable as these components have to be delivered under time pressure and not with maximum economy. Specialized laboratory units that perform high-throughput purification are often operated within the pharmaceutical industry. [Pg.131]

A fast solution for these separation problems is the use of generic gradients. Table 3.25 lists typical solvents and conditions for gradient runs for RP and NP systems. [Pg.131]

Phase system Adsorbent Weak solvent strong solvent [Pg.132]

Normal phase Silica Heptane Ethyl acetate [Pg.132]
