Abstract: A device for concentrating 99mTc pertechnetate and a method thereof are disclosed. The device includes a concentration device, a control device and a central processing unit. The concentration device is for concentrating 99mTc pertechnetate, the control device connects with each members of the concentration device, and the central processing unit is used for saving an automatic control program. The automatic control program is run by the central processing unit so as to detect and monitor weight as well as activity of the concentrated 99mTc pertechnetate. Due to the automatical control, the concentration quality and production efficiency of the 99mTc pertechnetate are improved. Moreover, the radiation dose received by users is reduced.

Abstract: An apparatus includes: a fully automated concentrator for 188Re-Perrhenate solution, a control box, and a control computer. The concentrator is controlled by the control box which obtains the signals from the computer. The operator can control it from far away, and monitor the processes such as liquid transfer, washing, filtration, collection etc. from a monitor for the computer. The apparatus can measure the radioactive activities of the collected concentrated 188Re-perrhenate solution and waste during operation; and can also measure the weights of the collecting bottle and solution. Hence the product quality and working efficiency can be increased, and radiation absorbed dose of an operator can be reduced.
