Abstract: The present invention relates to a method for controlling fraction collection of a target product 27 in a chromatography system 49 configured for cyclic purification performed on a sample comprising the target product 27. The method comprises determining trigger points for target product 27 collection in relation to presence of target product in the outlet; setting a first time period based on the trigger points within which the elution in the first cycle is captured; evaluating timing of the captured elution to identify the next time period; applying the timing to capture elution during the elution phase in the following cycle; and collecting the captured elution in the following cycle. The last three steps are repeated to capture the elution during the elution phase of the following cycles until no more target product 27 is desired.

Abstract: Inhaler counter (20) comprising a counter housing (390), a rocker arm (200) with a pawl (210), the rocker arm being pivotally supported by the housing and arranged to perform a rocker movement in response to a linear actuation motion, a return spring (220) for resetting the rocker arm, a ratchet wheel (230) engagable with the pawl to convert the movement of the rocker arm into an incremental rotational motion of an axle arrangement (240) advancing a display means (60), the axle arrangement further comprising a back rotation prevention means (280) in the form of a spring loaded friction brake and a worm gear, the display means comprising rotatable indicator means (120) with teeth that engage the worm-gear and a stationary scale.
