ELUTION GRADUEE [1 record]

English

Subject field(s)
  • Analytical Chemistry
CONT

A gradient method is recommended for samples that cannot be easily separated by isocratic methods because of their wide k range. In gradient elution the eluent strength is increased during the separation by changing the composition of the mobile phase. As a result, the analysis time is reduced and the quality of the separation is improved as well as the detection limit.

CONT

La technique du gradient d'élution permet souvent de séparer des solutés qui ne pourraient pas l'être par la méthode isocratique, même avec un mélange de solvants; elle est particulièrement efficace quand les constituants de l'échantillon sont de polarités très différentes.
