THERMODYNAMISCH STABILE WAESSRIGE MIKROEMULSION VON PERFLUORIERTEN KOHLENWASSERSTOFFEN, VERWENDBAR ALS BLUTGASKONTROLLE ODER BLUTGASSTANDARD.

摘要

An aqueous microemulsion for use as a blood gas control or calibrator comprising a perfluorinated inert liquid phase dispersed in a continuous pH buffered aqueous phase, the emulsion being a microemulsion which is thermodynamically stable at room temperature (20 DEG C), contains at least 10 weight percent of a perfluorinated inert liquid and contains two surfactants, the primary surfactant being non-ionic and water soluble and the secondary surfactant being hydrotropic and present in an amount sufficient to disorder any water-primary surfactant gels.
