A method for controlling timing of events in a microfluidic analytical devicemicrofluidic device and a timer microfluidic analytical devicemicrofluidic device The method comprises adding a liquid on a first end of a microfluidic analytical devicemicrofluidic device at a first time t0, the liquid flowing by capillarity towards a second end; producing, by a battery (12) included in the microfluidic analytical devicemicrofluidic device, energy from a second time tstart until a third time tend to feed an auxiliary device (16) connected to the battery (12), said tstart corresponding to the moment when the liquid contacts the battery (12); using a delivery energy time interval toperation of the battery (12) comprised between a time ton in which a voltage output of the battery (12) is above a threshold and a time toff in which the voltage output is below the threshold to control the duration of an event including a selective activation and deactivation of said auxiliary device (16), wherein the battery (12) being sized and composed to provide a given amount of energy.
