COMPOSITIONS AND METHOD FOR REDUCING THE RATE OF OXYGEN LOSS FROM AQUEOUS

摘要

Compositions and methods for reducing the rate of loss of oxygen from an oxygen containing solution. The composition comprises a choline salt such as choline chloride and a solution with a known amount of oxygen in the range between 10 and 300 mmHg. Additionally the composition optionally comprises a surfactant, an inert preservative and a biological buffer. The composition is used for increasing the life span of oxygen-calibration solutions.
