Micro Ramona Star is a newly developed radioactivity flowthrough
detector for the application of microflow or capillary HPLC.
Mira Star consists of a seperate detector unit and an electronic module
to position the detector as close as possible to the µ-HPLC system to
reduce peak broadening by long capillaries between the individual HPLC components.
