Abstract: A system for transferring a fluid sample in a fluid cell, includes a first and a second fluid circuit connected, respectively, to a first and a second inlet-outlet (1, 2) of a fluid cell (10), first injection elements (80) configured so as to inject, in series, into the first fluid circuit (11, 12, 13): a buffer solution, a first separation fluid volume followed by a fluid sample, then a second separation fluid volume and another buffer solution. The system includes first discharge elements arranged on the first fluid circuit near the first inlet-outlet (1), second injection elements (90, 91) arranged on the second fluid circuit (21, 22, 23) near the second inlet-outlet (2), and two-way circulation elements configured so as to circulate the fluid sample in two opposite directions in the fluid cell (10) without the passage of separation fluid into the fluid cell (10).
