Abstract
The particle sizes of 99mTc sulfer colloid and 99mTc antimony sulfide colloid EM were determined by gel filtration. These results were compared with those obtained by EM and by ultrafiltration. Gel filtration is suitable for particle-size determination below 100 nm, whereas above this size ultrafiltration provides the most convenient method.
