Hi guys, I want to calculate the size of nanoparticles by using data from a peak list obtained from the use of XRD. Can anybody help me calculate the particle size by using the scherrer equation? Thanks! :)
Particle size is the measurement of the diameter of an individual particle, typically expressed in nanometers (nm) or micrometers (μm).
A peak list is a data set that contains information about the intensity and position of peaks in a spectrum, typically obtained from analytical techniques such as X-ray diffraction or laser diffraction.
Particle size can be calculated from a peak list by using the peak position and the known wavelength of the analytical technique (e.g. X-ray or laser) to determine the diffraction angle, and then applying the appropriate mathematical equations for the specific technique to convert the angle to a particle size measurement.
Yes, there are different methods for calculating particle size from a peak list depending on the analytical technique used. For example, the Scherrer equation is commonly used for X-ray diffraction, while the Mie theory is used for laser diffraction.
The accuracy of particle size calculations can be affected by factors such as the quality of the peak list data, the accuracy of the analytical technique, and potential interferences from other particles or impurities in the sample. It is important to carefully evaluate and validate the data and methodology used for particle size calculations.
