High count rates of lithium ions in an AMS measurement system for 14C were traced to the lithium content
in the quartz tubes used in the graphitzation of the samples. The lithium contamination was nearly eliminated by the use of borosilcate glas reaction tubes at a lower reaction temperature. The ion beam curent and the measurement precison of the isotope ratio were not afected.
