Detecting Cells in a Cell Suspension

摘要

The embodiments relate to an arrangement for quantifying cells. The arrangement includes a magnetic field-sensitive sensor having a 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. 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. 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 includes a channel for conducting the cell suspension past the sensor elements.

1. An arrangement for quantifying cells while distinguishing between at least two different sizes of cell types, cell conglomerate types, or cell types and cell conglomerate types in a cell suspension, the arrangement comprising:
a magnetic field-sensitive sensor comprising a first pair of sensor elements and a second pair of sensor elements; and a channel for guiding the cell suspension past the sensor elements, wherein the sensor elements of the first pair comprise a first spacing of between half and double a first mean size of a first type of cell or cell conglomerate to be measured, wherein the sensor elements of the second pair comprise a second spacing of between half and double a second mean size of a second type of cell or cell conglomerate to be measured, and wherein a third spacing between a sensor element of the first pair and a sensor element of the second pair that are closest to one another is greater than the larger of the first and the second mean sizes.
