Improvement of the detection limit of magnetically labelled samples

摘要

The invention describes a device and a method for the reduction of the detection limit for magnetic labeled molecules. This is due to the shielding of the sensor and the electronic device is achieved by the earth''s. Furthermore, the sample carrier in front of the measurement by means of a magnet is cleaned and to its properties of the magnetization calibrated so that these values after measurement with a sample can be debited.
