Such a device for instance may be used to determine the efficiency of a pollutant removal structure such as a filter of an air purifier by guiding a sample of the 'dirty' air through the first inlet and a sample of the air purified by the pollutant removal structure through the second inlet. An air purifier system including such a fluid sensor device (10), a method (300) of operating such an air purifier system and a computer program product for implementing such a method are also disclosed.

    • The invention proposes a method and device for sensing a liquid that contains positively charged particles and/or negatively charged particles. An electrical field is imposed to the liquid by applying a voltage to a positive electrode and a negative electrode disposed in the liquid, for attracting the negatively charged particles toward the positive electrode to concentrate the negatively charged particles in a first part of the liquid and attracting the positively charged particles toward the negative electrode to concentrate the positively charged particles in a second part of the liquid. A first sensing result is obtained by sensing at least one part of liquid of the first part of the liquid, the second part of the liquid, and a third part of the liquid in which the negatively charged particles and the positively charged particles are deconcentrated. Accordingly, the sensing is conducted in at least one part of liquid in which the concentration of the charged particles is changed. Since the concentration of the particles in the liquid impacts the sensitivity of the sensing of the liquid, it is possible to improve the sensitivity.
    • 本发明提出了一种用于感测含有带正电荷的颗粒和/或带负电粒子的液体的方法和装置。 通过向设置在液体中的正极和负极施加电压而向液体施加电场,用于将带负电荷的颗粒吸引到正极以将带负电荷的颗粒集中在液体的第一部分中并吸引 带正电的颗粒朝向负极,以将带正电的颗粒集中在液体的第二部分中。 通过感测液体的第一部分,液体的第二部分和液体的至少一部分液体获得第一感测结果,其中带负电的颗粒和带正电的颗粒被分散在其中。 因此,感测在至少一部分液体中进行,其中带电粒子的浓度被改变。 由于液体中颗粒的浓度会影响液体的感测灵敏度,因此可以提高灵敏度。

    • The invention proposes a sensor device (10) and a method of sampling. The method comprises the steps of: A. adding a sample to a chamber (12) in which magnetic particles (P) are provided, the sample including a target component (T) and the chamber (12) having a detection surface (122); B. exerting a magnetic force on the magnetic particles (P) to attract the magnetic particles (P) to the detection surface (122), wherein bound magnetic particles that capture the target component (T) in the magnetic particles (P) are held at the detection surface (122), and unbound magnetic particles that capture no target component (T) in the magnetic particles (P) are held at the detection surface (122) as well; C. altering the magnetic force exerted on the magnetic particles (P) to release the unbound magnetic particles from the detection surface (122); D. measuring the amount of the bound magnetic particles that are held at the detection surface (122); E. determining whether the amount of the bound magnetic particles that are held at the detection surface (122) is above a predetermined threshold; if no, performing the following steps of: exerting the magnetic force on the magnetic particles to attract the magnetic particles (P) to the detection surface (122); draining at least part of the sample out of the chamber (12) and adding a new sample to the chamber (12); altering the magnetic force exerted on the magnetic particles to release the unbound magnetic particles from the detection surface (122); and going back to perform the steps B to E. By doing so, 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.
