Benzene line requirements

Ane of Modern Conventional Carbon Dating laboratory is based on Radioactivity measurement by Liquid Scintillation Counting (LSC). As for LSC based Conventional Carbon Dating laboratory it is required modern liquid scintillation counter (spectrometer) like: QUANTULUS Liquid Scintillation Spectrometer or Tri-Carb Liquid Scintillation Counters both produced by PerkinElmer Inc.. Benzene as counting sample is produced using benzene line.
