Used forblood cell counter reagent
are: cleaning fluid, leukocyte diluent and sheath fluid, etc. Below
are perlong medical equipment net woven through the analysis about the sheath
fluid in the blood cell analyzer in the action principle and other reagent to
the instrument testing affect the result.
Most high-end blood analyzer in order to improve the accuracy of detection, applied the sheath flow principle, the main application of the reagent is sheath liquid. Sheath flow form have single sheath flow and sheath flow, the purpose is that the cells are a straight line through testing department. In the sheath flow pool (generally divided into before and after sheath flow pool or internal and external sheath flow pool) the positive pressure mode will sheath liquid injection, sheath fluid in the sheath flow pool formation fixed direction of eddy current, at this time again sample with positive pressure form injection,
then all the specimens without exception can only according to the flow direction through the sheath flow pool, creating sheath flow direction, in this direction on resistance count or suction photometer number or light scattering count, can fully guarantee correct counting each cell, and ensure enough through the quantity, but also can assure count after the sample will not return back, with sheath flow protection, sample will be in the sheath flow positive center through the
Count pipeline or hole, so won't appear deviation of the interference signal, can guarantee that every cell of the free. Due to the sheath liquid need wrapped around the tested sample after detection department accept laser irradiation or resistance KangFa count,
so sheath fluid cleanliness, absorbance, pH value, osmotic pressure will meet the hematolgy analyzer design requirements, otherwise will be to the instrument testing which may affect the results.
Some blood cell analyzer need in diluent to add glutaraldehyde and sodium dodecyl sulfate and reagent, the purpose is counting on blood cells before be volume spherize processing, so count can avoid the size difference on the impact of blood count.
Above this paper expounds the blood cell analyzer reagent action principle and the influence of the detection results, from which we can see that every kind of reagent has a different effect, how to prevent the influence of medical reagent to the test results, it needs us in perfect reagent quality control system, and the development of suitable for supporting the reagent and instrument of standard material things work hard.
