Impurities can cause altered in vivo bio distribution after administration which can result in an unnecessary radiation dose to the patient. 3 chromatography paper sheets were cut into 1 cm × 8 cm strips and placed into empty 10 ml glass pharmaceutical vials.This study developed a type of paper chromatography to determine the radiochemical purity of radioactive microspheres.Microsphere preparation The present study developed a type of paper chromatography for determination and comparison of the radiochemical purity of radioactive yttrium-90 microspheres produced by sol gel method and different composition 1) TEOS: H, (Az spheres) [17].The radiochemical purity of Az sphere 1 was more than 99% in the saline and acetone solutions.The results indicate that the low level of chemical impurities in the Azer and Az spheres make them suitable for medical applications.Published by Houghton Mifflin Harcourt Publishing Company.
