Abstract
Method and arrangement (10, 20) for preparing samples (15, 27) submergible in a liquid medium. The arrangement includes a carrier structure (11). The carrier includes a device (13, 23) for controllable generation of a magnetic field through influence of a control signal to attract at least part of the at least first and second type of samples (15, 27) towards specific locations on the carrier when connected to a first control signal and to repel at least one of the first or second type of samples when connected to a second control signal.
Claims38
A liquid medium submergible sample preparing arrangement suitable for enhancing detection of different samples comprising at least first or second type of samples, said arrangement comprising:
- a carrier structure including a device for controllable generation of a magnetic field through influence of a control signal to attract at least part of said at least first and second type of samples towards specific locations on said carrier when connected to a first control signal and to repel at least one of said first or second type of samples when connected to a second control signal.
A method for analyzing different samples in an analysis arrangement in a fluid medium, said samples being provided with magnetic members, the method comprising:
- providing an arrangement comprising a carrier structure, a testing section on said carrier structure provided with a magnetic field generator upon reception of a control signal, wherein said testing section is provided with a test material reactive to at least one type of said samples;
- and
- attracting said different samples to said testing section by generating a magnetic attraction force, and after reaction, repelling samples not being of said one type.
