为了测定任何大小的单一种粒的渗出物,开发了一种简易方法。用光谱仪于260nm处测定种子渗出物的光密度,且与其电导性测试方法的数据作比较,从大量测定样品的结果看,其方法非常灵敏和简易。
In order to determine single particle size exudates of any size, a simple method has been developed. The optical density of the seed exudate was measured at 260 nm with a spectrometer and compared with the data of the conductivity test method. The method was very sensitive and simple to determine from the results of a large number of sample measurements.
