| Résumé : |
While the chemical composition of a substance is conveniently determined by analytical chemical means and the gross structure assessed by microscopical techniques, the borderline area—ranging from tens of ángströms to a few millimicrons—could well be investigated using an electron microscope. One can not only observe the various entities and study their morphology but also follow the reactions that a substance undergoes when subjected to several treatments.
The advantages of modern electron microscopy include, apart from the require ment of small quantities of sample, stereoscopic view, possibility of heating or cooling the sample, and observation of the specimen under moist conditions.
The results obtained from electron microscopical analyses can broadly be discussed under the following headings :
(a) Raw material-Collagen
(b) Tanning materials
(c) Effect of pre-tanning and tanning operations on collagen
(d) Other modifications such as irradiation
(e) Miscellaneous |
