Pumping system for chromatography applications

Abstract:

A pumping system for compressible fluids comprises a first pump having a first pump outlet and a second pump having a second pump outlet. The first pump outlet and the second pump outlet merge in a junction which is in fluid communication with a main outlet. The pumping system further comprises a control to regulate the output pressure of the second pump on the basis of a measurement of the output pressure of the first pump. The corresponding method of operating a pumping system is also disclosed.
