Abstract: The invention relates to a method for the preparation of porous polymeric fibres comprising functionalised or active particles. By extruding a mixture of one or more dissolved polymers with particulate material a porous fibre is obtained in which the particulate material is entrapped. Extrusion of the fibre occurs under two-step phase inversion conditions. In particular the porous fibres can be used for the isolation of macromolecules such as peptides, proteins, nucleic acids or other organic compounds from complex reaction mixtures, in particular from fermentation broths. Another application is the immobilisation of a catalyst in a reaction mixture.

Abstract: The present invention relates to a motor system, a stepper motor and a rotor therefor. More in particular, the present invention relates to detecting, in a motor system, an angular position of a rotor of an electric stepper motor. The motor system according to the present invention comprises: a stepper motor, the stepper motor comprising a stator and a rotor, wherein the stator comprises a cavity in which the rotor is arranged, and a plurality of stator coils arranged around a circumference of the cavity, the plurality of stator coils being configured to drive the rotor to rotate in a rotational direction, and wherein the rotor comprises a rotor body having a plurality of rotor poles that are irregularly spaced along a circumference of the rotor body; a driving unit configured to drive each stator coil using a respective driving signal to thereby cause the rotor to rotate; and a position determining unit. The position determining unit is configured to, while the rotor is rotating: measure a current through one or more stator coils among the plurality of stator coils, each current comprising a superposition of at least a driving current as a result of driving a corresponding stator coil and an induced current resulting from a changing magnetic flux through said corresponding stator coil due to the rotating rotor; and determine an angular position of the rotor based on the measured current(s) and a known spacing between the plurality of rotor poles.

Abstract: A method and system for concentrating an analyte (A). Liquid droplets (D) of an extractant liquid (Le) are adhered to a wall (10w) of a container, e.g. capillary tube. A sample fluid (Fs) comprising the analyte (A) is provided in the container (10) to contact the liquid droplets (D). The analyte (A) has a higher solubility in the liquid droplets (D) than in the sample fluid (Fs). This causes the analyte (A) to be extracted from the sample fluid (Fs) and concentrated in the liquid droplets (D). After extraction, the liquid droplets (D) are collected, e.g. scraped, from the wall (10w) for obtaining the concentrated analyte (A). A concentrated liquid (La) can be formed by collecting the liquid droplets (D) from the wall (10w). The analyte (A) can be measured in the concentrated liquid (La) using any suitable measurement technique.
