粒度儀測試縱坐標代表什么
|
||||
| 粒度儀測試給出三個圖,一個是強度(intensity),一個體積(volume),一個是數(shù)目(number),請問以強度為縱坐標的時候代表什么?強度指的什么,具體什么意義 |

Intensity Distribution The fi rst order result from a DLS experiment is an intensity distribution of particle sizes. The intensity distribution is naturally weighted according to the scattering intensity of each particle fraction or family. For biological materials or polymers the particle scattering intensity is proportional to the square of the molecular weight. As such, the intensity distribution can be somewhat misleading, in that a small amount of aggregation/ agglomeration or presence or a larger particle species can dominate the distribution. However this distribution can be used as a sensitive detector for the presence of large material in the sample. |

Volume Distribution Although the fundamental size distribution generated by DLS is an intensity distribution, this can be converted, using Mie theory, to a volume distribution or a distribution describing the relative proportion of multiple components in the sample based on their mass or volume rather than based on their scattering (Intensity.) When transforming an intensity distribution to a volume/mass distribution, there are 4 assumptions that must be accepted. • All particles are spherical • All particles are homogeneous • The optical properties of the particles are known, i.e. the real & imaginary components of the refractive index • There is no error in the intensity distribution |
