STABILE HÄMOGLOBINREFERENZLÖSUNG.

摘要

A stable reference solution for calibrating and monitoring blood gas instrumentation is disclosed. The solution comprises an aqueous mixture containing a hemoglobin solution derived from a mammalian source which comprises at least about 95% reduced hemoglobin. The solution additionally contains a bicarbonate buffer and a metal catalyzed methemoglobin reducing system and an organic buffer. To provide a control element having a variety of properties similar to fresh, whole, human blood, the reference solution is stored in a sealed ampule under an inert atmosphere containing CO2 until just prior to use. The ampule is subsequently opened and the solution is equilibrated with a gas mixture having components which provide gasses in a physiological range to the solution. The solution is characterized by exhibiting properties similar to fresh blood subsequent to equilibration and an extended storage life prior to equilibration.
