title: An improved procedure for the electrochemical determination of serum ionized calcium.
abstract: The "Orion model 99-20 serum calcium flow-through system" has been rendered insensitive to protein poisoning by the plascing of a dialysis membrane in front of the electrode membrane, making the addition of trypsin and triethanolamine to standards unnecessary. Flow dependency of the results obtained has been investigated.
