The sample includes a target component (T) and the chamber (12) has a detection surface (122). A magnetic force is exerted on the magnetic particles (P) to attract the magnetic particles (P) to the detection surface (122). The bound magnetic particles that captured the target component (T) in the magnetic particles (P) and the unbound magnetic particles that captured no target component (T) in the magnetic particles (P) are held at the detection surface (122). At least part of the sample is drained out of the chamber (12) and a new sample added to the chamber (12). The magnetic force exerted on the magnetic particles (P) is altered to release the unbound magnetic particles from the detection surface (122). An amount of the bound magnetic particles that are held at the detection surface (122) are measured. The target component (T) is preconcentrated by repeating the steps of magnetically binding the target component (T) from the newly added sample and washing the detection surface (122) from unbound magnetic particles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor device and a method of sampling","description":"A sample is added to a chamber (12) in which magnetic particles (P) are provided.
