✦ Synopsis

The study presented here was designed to provide information on the nature of fibres subjected to the action of raised temperature and on the possibility of determination of the incinerated material. X-ray powder diffraction was used as the most reliable method of identifying the composition of crystalline substances. The subject of study was natural and synthetic fibres, the most frequently used in Poland in recent years; for the simulation of phenomena caused by the action of raised temperature the fibres were incinerated in a muffle furnace. The samples of analyzed incinerated fibres were of different chemical species, and those differences were more evident for natural fibres, where from five to seven chemical species or minerals were detected. In specific forensic cases related to incinerated fibres FTIR, SEM/EDX, polarized light microscope and X-ray powder diffraction techniques should be used simultaneously to give full results.

## Abstract **Summary:** The average lateral dimensions of cellulose microfibrils in paper sheets can be determined from the width of X‐ray Bragg peaks at half the maximum height. The method assumes it is the finite size of the crystallite which is the main contributor to peak broadening in the dir

A method of analyzing mixtures of APIs and excipients using X-ray powder diffraction is described. It uses a simple algorithm based on linear regression in which the pure component phases are fitted to the mixture pattern using linear least squares. Unlike many methods that use only the peaks in the
