WebDynamic light scattering DLS measures the correlation function of intensity fluctuations. This can then be mathematically converted into an intensity size distribution, and from … WebThe quality parameters: optical activity (α°), spectra of dynamic light scattering by intensity, volume, and number ("I-d"; "V-d"; "N-d"), electrokinetic potential (ξ) values, and photon pulse count per second (Count Rate, kcps) corresponded to the results obtained for pharmaceutical dosage forms.
WebOct 27, 2015 · Number是粒径一次方的加权平均数,Surface是粒径二次方的加权平均数，Volume是粒径三次方的加权平均数，Intensity是粒径六次方的加权平均数。 所以才会依次增大，而且Intensity更是大的可怕。 具体哪个对你最有用就要看你想表征什么粒径了。 但是如果你的粒径大分散性很好的话，这四者的数据应该基本相等。 查看全部回复 我也来说 … WebThe principles of dynamic light scattering The method of dynamic light scattering (DLS) is the most common measurement technique for particle size analysis in the nanometer range.
