Abstract
A liquid scintillation composition especially useful for gradient elution chromatography comprising an aromatic liquid capable of capturing energy from radiation by radio-tagged compositions, at least one fluor, at least one low molecular weight alcohol and a surfactant comprising a polyoxyalkylene unit and a straight chain alkyl unit. Preferably, the surfactant comprises an ethoxylated or propoxylated fatty alcohol or fatty acid in which the moles of ethylene or propylene oxide range from 5 to 25 and the length of the alkyl chain is between 6 and 20 carbon atoms.
