This is the rationale why in gradient elution the composition of your cell period is assorted commonly from very low to significant eluting energy. The eluting toughness on the mobile section is reflected by analyte retention moments, as the large eluting energy accelerates the elution (leading to shortening of retention occasions). As an example,
