to characterize better the principal components found in [ 99mtc ] pyrophosphate preparations used for diagnostic bone and heart scanning , these were studied in two ion-exchange chromatographic systems : ( a ) deae-cellulose in pyrophosphate form at ph 6.0-7.5 , and ( b ) deae-cellulose in perchlorate form at ph 3.7-4.8 .
