The two kinds of liquid scintillation counters (LSCs) from PerkinElmer, Quantulus GCT 6220 and Quantulus 1220, have been compared on their basic performances, i.e., background count rate, counting efficiency, α/β discrimination, and instrument stability, by determining the radioactivity of the radionuclides of 3H, 14C, 241Am, 90Sr/90Y, 60Co, and 137Cs. Except for the highlight of Quantulus GCT 6220 in stability and that of Quantulus 1220 in background for α counting, the two kinds of LSCs are comparable in the basic performances to each other.
