Such as liquid chromatography of the sample solution should be selected chromatographic mobile phase or HPLC elution solvent strength is weak;

If chromatography sample solution use a high performance liquid chromatography mobile phase chromatographic Elution solvent strength is low or;

If the liquid chromatography sample solution selects the chromatograph flowing suitably or the chromatograph elution intensity weak solvent;

If the sample liquid chromatography solvents are advised to choose chromatography mobile photo or color spectrum intensity washed weaker solvents;

If chromatography sample solution use a high performance liquid chromatography mobile phase chromatographic Elution solvent strength is low or;
