Merenje raspodele veličina čestica metodom difrakcije laserske svetlosti

U ovom tekstu opisan je princip rada instrumenta za merenje raspodele veličina čestica Mastersizer 2000, Malvern Instruments Ltd., UK, koji radi na principu analize difraktovane svetlosti. Na konkretnim primerima, pokazali smo da metoda nije rutinska, da se ne svodi na unošenje uzorka u uređaj i pritiskanje dugmeta. Pokazali smo da način pripreme uzoraka za merenje i tačnost rezultata zavise od fizičkih i hemijskih karakteristika analiziranog materijala.
The paper deals with the main principles of determination of particle size distribution using Mastersizer 2000, Malvern Instruments Ltd., UK. On the example of several problems we have demonstrated that the method is not a routine one and that the measurement procedure is not limited to entering a sample into the dispersion unit and pressing the button. Furthermore, we have shown that the sample preparation method and, therefore, the accuracy of results conclusively depend on physical and chemical properties of the analyzed materials.
