Morphological and elemental analysis of alpaca hair (Vicugna pacos) using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM – EDX)
The aim of studies was to evaluate the microstructure and elemental compositions of alpaca hair. The hair from eight alpacas, which came from different part of Poland, were analyzed by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). The quantitive analysis was performed for nutritionally important elements (calcium and phosphorous), elements, which are part of building blocks of hair structure (silicon and sulfur) and trace elements (copper, zinc, selenium). Moreover, the elemental mapping was carried out. The SEM images showed that microstructure of hair is irregular and rough. The average diameter of hair is 32,27 ± 4,06 µm. The obtained results showed content of elements in hair and also their distribution in the structure of hair. This findings can be a good benchmark for further studies. .
Key words: alpca, hair analysis, scanning electron microscopy, energy-dispersive X-ray spectroscopy
