摘要： A method of analyzing a sample fluid containing organic microobjects is proposed. The method comprises the steps of: up-concentrating (S1) the microobjects by removing, in a total time T1, a volume V1 of the sample fluid from the upconcentrate sample microobjects; immersing (S2) the microobjects in a transfer fluid, or leaving the microobjects in a remaining portion of the sample fluid, the remaining portion of the sample fluid then providing the transfer fluid; filtering (S3), in a total time T3, a volume V3 of the transfer fluid by a filter, thereby accumulating the microobjects on the filter; and generating (S4) an image of the microobjects accumulated on the filter; wherein the throughput V1/T1 of the step of up-concentrating (S1) is greater than the throughput V1/T1, of the step of filtering (S3). The filter may be a second filter, and the step of up-concentrating (S1) may involve: filtering the sample fluid by a first filter, thereby accumulating the microobjects on the first filter. An apparatus or system for analyzing a sample fluid containing organic microobjects is also disclosed.
