Systems and methods for processing a fluid sample

A system for processing a fluid sample containing a target analyte, the system comprising:

• a fluid conduit comprising a first open end and a second open end, wherein the first open end is configured to receive the fluid sample and the second open end is configured to release the fluid sample;
• and
• a first electromagnetic trap disposed between the first open end and the second open end, wherein the first electromagnetic trap comprises at least one electromagnet configured to receive an electrical signal to generate a magnetic field within the first electromagnetic trap.

A method for processing a fluid sample containing a first target analyte, the method comprising:

• introducing a first batch of magnetic particles into a fluid conduit, the fluid conduit comprising a first open end, a second open end, and a first electromagnetic trap between the first open end and the second open end, wherein the first electromagnetic trap is defined by a first volume, and wherein the magnetic particles comprise a first receptor to bind the first target analyte in the fluid sample;
• and
• introducing a flow of the fluid sample through the fluid conduit from the first open end to the second open end, wherein the fluid sample comprises a second volume greater than the first volume.
