Preliminary Study on Measurement of ²²Na Tracer With Liquid Scintillation Counting in Botanical Research

A new experimental means which measured radioactive count on ²²Na plant tracing was found. Some factors influencing on count which included different sample disposals, water content of plant, dosage of twinkle liquid, and chemistry quenching were studied. And small centrifugal tubes were used in experiment. The tube can reduce the cost, and make the experiment simple and reliable.
