Method and apparatus for measuring the radioactivity in column eluates |
摘要 |
A method for measuring the radioactivity in eluates from liquid chromatography columns in which a portion of the eluate stream is split off and mixed with a scintillation fluid in a timed sequence wherein the volume of eluate and the volume of scintillation cocktail are quantitatively and reproduceably controlled. An apparatus for the practice of this method comprising a two-position valve on the affluent stream, a two-position valve on a pumped closed loop of scintillation cocktail a means for simultaneously setting the position of each valve and a mixing chamber discharging to a scintillation counter is also described. By the practice of this method, it is possible to determine the radioactivity of the eluate as well as to preserve a sample of the eluate for further analysis.
