1. a kind of sample processing device (100,200), it, which has, is used in first sample chamber (SC1) and the second sample chamber(SC2) device of generation magnetic field (B) in, the first sample chamber (SC1) and second sample chamber (SC2) are in x directionsIt is upper to position adjacent to each other and with the bottom upwardly extended on the x directions and in the y side substantially vertical with the x directionsPortion (102), the equipment includes:

  • A) the first electromagnet (110,210), it has horseshoe-shaped magnetic core (112,122) and with can be arranged at described theIt is below one sample chamber (SC1), in said y direction the first pole pair close to each other (111,111'"'"', 211,211'"'"');

    B) the second electromagnet (120,220), its have can be arranged at it is below second sample chamber (SC2), in the ySecond pole pair close to each other on direction (121,121'"'"', 221,221'"'"');

    C) control unit (130), it is used to be individually controlled first electromagnet and the second electromagnet so that different electromagnetsThe neighbouring magnetic pole (211,221 of (210,220);

    211'"'"', 221'"'"') operated under identical polar pattern or opposite polarity pattern,The neighbouring magnetic pole (211,221 of different electromagnets (210,220) described in the identical polar pattern;

    211'"'"', 221'"'"') with identicalPolarity, and in the neighbouring magnetic pole (211,221 of different electromagnet (210,220) described in the opposite polarity pattern;

    211'"'"'、

    221'"'"') there is opposite polarity, wherein mixing the identical polar pattern and described opposite with the ratio of predetermined timePolar mode.
