    摘要: A cleaning solution for automatic biochemical analyzers includes: at least one anionic surfactant, at least one nonionic surfactant, an alkali metal hydroxide, an alkali metal citrate, and a buffering agent stabilizing the pH value above 13.0. In some embodiments, the cleaning solution provides low residual rate of proteins, low residual rate of lipids, desirable within-batch repeatability in clinical testing, low level of cross-contamination, and low level of reactant deposit after cleaning, without affecting test results of the biochemical analyzer. In some embodiments, the cleaning solution has no corrosive effects on the liquid path and reaction cup of the analyzer. The ingredients of the cleaning solution may also be biodegradable.

    摘要: The present invention relates to a processing method for long-term stabilization of biological red blood cell volume. The red blood cells can be further used in reference materials and calibrators of a hematology analyzer. The method of the present invention comprises contacting the sample with a solution comprising a membrane-fixation reagent and an aldehyde for a processing period to terminate or slow down the red blood cell metabolism. It is provided by experiments that such process enables the volume of the red blood cells to be stable in a period over 120 days.
