摘要： A method for dispensing droplets of a liquid to a microsystem in the form of a disc comprising a discrete target area (TA1) in its surface. The method is characterized by comprising the steps of: i) providing A) said disc on which said target area is discrete and on which there is triggering mark, and B) a dispenser arrangement comprising: a) a spinner for rotating the disc around its axis, b) a drop dispenser which is capable of dispensing droplets to TA1, c) a fixed trigger position outside the disc, and d) a controller which is capable of triggering the dispensation of a droplet into TA1 as a function of the triggering mark passing the trigger position via a dispensing signal; ii) placing the disc in the spinner and programming the controller with values for dispensing parameters that will give dispensation of the droplets to TA1; iii) dispensing the droplets, preferably while the disc is spinning. The disc may comprise several discrete target areas. The target area(s) may be part of one or more microchannel structures and function as inlet ports for liquid. The invention also comprises the dispenser arrangement as such.

摘要： The present invention concerns detector arrangements and a method that are adapted to measure radiation from detector areas in the surface of a microfluidic device. The arrangement comprises a detector unit with a detector head and other units enabling for the detector unit to collect radiation from the detection areas.
