Abstract: L'invention concerne un procédé de caractérisation de polymère à base d'hydrates de carbone reposant sur l'identification d'au moins deux agents de liaison liés au polymère. De préférence, la liaison est déterminée par contact entre le polymère et un substrat renfermant des premiers agents de liaison de saccharide fixés en des points préétablis du substrat. Le polymère entre en contact avec le substrat dans des conditions qui permettent la formation d'un premier complexe entre le premier agent de liaison de saccharide et le polymère. Un second agent de liaison de saccharide, comprenant de préférence un marqueur, entre également en contact avec le polymère dans des conditions qui permettent la formation d'un second complexe entre le second agent de liaison et le premier complexe. L'identification des premier et second agents de liaison permet de caractériser le polysaccharide.

Abstract: The present invention provides a method and apparatus for producing fine particles. According to the production method, a molten material 1 which has been formed by melting a raw material to be formed into fine particles is supplied in the form of droplets 1a or a jet flow to a liquid coolant 3, and a vapor film formed so as to cover the molten material supplied to the liquid coolant 3 is forcedly broken to promote vapor explosion, thereby forming and cooling fine particles for solidification. The production method and apparatus can readily produce fine particles from a raw material having a high melting point, and can relatively readily produce submicron fine particles; such particles are difficult to produce by mean of the previously developed technique. The method and apparatus can produce amorphous fine particles, or polycrystalline fine particles having a target particle size by regulating conditions for fine particle formation and for cooling-solidification.
