The invention relates to a set comprising, on the one hand, a pipette (12) having a pipette orifice (11) and, on the other hand, a cartridge (1). The cartridge comprises: a housing (2); a chamber, containing sorbent (5), provided in the housing; an inlet (8) that connects the chamber to the outside of the housing and that has an inlet orifice (10) on the outside of the housing; an outlet that connects the chamber to the outside of the housing; an inlet closure (9) that is permeable to fluid and impermeable to the sorbent, which inlet closure extends over the entire inlet passage; an outlet closure (6), such as a mesh, that is permeable to fluid and impermeable to the sorbent, which outlet closure extends over the entire outlet passage; wherein the pipette orifice can be accommodated in the inlet orifice. The invention furthermore relates to a method for applying the sample to a sorbent by means of a pipette. In addition the invention relates to an analytical method wherein a sample to be analysed is transferred by means of a pipette to a cartridge and this sample is applied to a sorbent contained in said cartridge and the sample, or at least an analyte present therein, is eluted from the sorbent using an eluent and the sample, or at least the analyte, is then subjected to an analysis. <IMAGE> |
