Находясь в кювете (в зоне измерения, на пути луча лазера) частицы рассеивают
свет. Индикатриса рассеяния (угловая зависимость интенсивности рассеянного
излучения) определяется размером частиц, их оптическими характеристиками и
длиной волны лазера (которая является постоянной).
Экспериментальные значения индикатрисы рассеяния получаются в результате
усреднения данных о светорассеянии, регистрируемых с частотой 1 кГц. ...Установив программно длительность анализа около 20 секунд, фактически выполняется 20000 измерений.
Процедура восстановления распределения частиц по размерам по данным
угловой зависимости рассеянного света (деконволюция) производится программным обеспечением анализатора на основании оптической модели: полной теории Ми или приближения Фраунгофера. Приближение Фраунгофера является частным случаем теории Ми, в основе которого лежат следующие допущения:

Choosing the correct analysis mode
The analysis model tells the computer what the expected shape of the result graphwill be. There are five choices available; polydisperse, multimodal, monomodal,very polydisperse, and compressed range.. Polydisperse model does not assume anything about the shape of the re-sult graph.. Multimodal model assumes that there will be one or more distinct peaksin the results graph - indicating that there are several distinct sizes of parti-cles.. The monomodal model assumes that there will only be one peak in the re-sult graph - indicating that there is only one size of particle.. Very polydisperse is similar to polydisperse but is used for a few specialcircumstances. (Mastersizer X only).. Compressed range analysis has a reduced upper size limit and is meantfor use with dry powder and spray measurements. (For Mastersizer S only)

The presentation
As stated earlier, the Mie theory needs to know specific information about the structure of the sample and the medium it is suspended in so that it can calculate exactly how light passes through them. The specific information required is the relative refractive index of the particle to be measured, the particle adsorption(imaginary refractive index) and the refractive index of the medium that the particle is suspended in (dispersant). Once the Malvern software knows this information it can calculate the expected scattering pattern from these particles. This scattering pattern is known as the"presentation". The presentation is identified by a label of the form "3OHD".The details of how these codes are made up will be discussed later. There are three ways of selecting a presentation.. The easiest way is to use one of the four "default" or "system" presentations.
These are;
Fraunhofer (3$$D). This is the presentation that is used when you wish
to use the simpler Fraunhofer model.
Standard - Wet (3OHD). This is a presentation that takes a "middle of the road" value for the refractive index and adsorption of the sample andassumes that the particle is suspended in water.
Standard - Dry (3RHA). This presentation is the same as standard-wetexcept assumes that the particle is suspended in air.
Reference Reticle (3$$1). This is the presentation that is used when the Diffraction Reference Reticle accessory is used to validate the system.Obviously this will only be used if you have the accessory.
