Abstract (en)
[origin: WO2013189722A1] The invention relates to an arrangement for quantifying cells while differentiating between at least two different sizes of cell types and/or cell conglomerate types in a cell suspension, comprising a magnetic field-sensitive sensor which has at least one first and second pair of sensor elements. The sensor elements of the first pair are connected as part of a Wheatstone bridge and have a first spacing of between half and double a first average size of a first cell or cell conglomerate type to be measured. The sensor elements of the second pair are connected as part of a Wheatstone bridge and have a second spacing of between half and double a second average size of a second cell or cell conglomerate type to be measured. A third spacing of the two closest sensor elements of the pairs is greater than the larger of the two average sizes. The arrangement also comprises a channel for conducting the cell suspension past the sensor elements.
