A simple automated system for the routine production of 99mTc by methyl-ethyl-ketone extraction
Abstract
A relatively simple, automated system for the rapid, efficient and safe routine production of 99mTcM from 99Mo03 by the methyl-ethyl-ketone (MEK) extraction technique is described. The 4 phases of the extraction process - bubbling of air, phase separation, drawing off of 99mTc in MEK, and evaporation to dryness, are controlled by an automatic timer, suction-pressure pump and solenoid switches. The eluate was found to contain neither bacterial organisms or pyrogens nor significant levels of alumina and radio-isotopic impurities. With this system it is possible to make use of locally produced 99Mo, even of low specific activity for the routine production of 99mlc in any concentration required.
