<p>A flow cell (24) for liquid scintillation counting having a spool (35) wound with a length of light transparent tubing (40) provides a variable volume of sample solution for analysis by selectively winding the spool with a select length of tubing, thus controlling sensitivity of analysis and maintaining resolution of separated constituents in the sample. The flow cell comprises a spool (35) rotatably held within a framework (34) and which may be covered with a transparent material.</p> |
