The RAMONA* Quattro is our ultra sensitive β-HPLC-flow-detector. RAMONA* Quattro contains 4 beta-radioactivity-coincidence-flow-detectors in 1 instrument. RAMONA* Quattro applies 4 pairs of 2 x 1 1/8” photomultipliers in coincidence to arrange 4 flow cells, one after the other. 4 coincidence-detectors measure the beta-radioactivity in the HPLC-flow individually.
