冻干健康人血浆成品(以下简称血浆)用0.1％枸橼酸液溶解后呈黄色微混浊液体,由于产品质量和生产工艺的差异,形成的混悬度不尽相同,中国生物制品规程对此未作具体规定。国内普遍采用目视比浊法进行质量控制,这种方法误差较大,判别时的光线、背景的色深、操作者的辨浊视力等均带来直接影响;为此,我们根据混浊液在一定波长范围其浊度与吸收度呈线性关系,试用可见分光光度计 Lyophilized healthy human plasma products (hereinafter referred to as plasma) with 0.1% citric acid solution was yellow micro-turbid liquid, due to product quality and production process differences, the formation of the degree of suspension vary, China Biological Products Regulation No specific rules. Visual turbidity method is generally used for quality control in our country. The error of this method is large, and the light color, the color depth of the background, the operator’s opacity of eyesight and so on have a direct impact. For this reason, A certain wavelength range of its turbidity and absorption showed a linear relationship, the trial visible spectrophotometer
