Abstract

L'invention concerne un procédé de préparation d'échantillons en vue de la réalisation d'analyses de volatilisation et de spectrométrie de masse sur des molécules non volatiles à poids moléculaire élevé. Elle concerne également des molécules photo-absorbantes caractérisées par des vitesses de sublimation importantes à température de la pièce sous vide, lesquelles molécules, qui comportent, de préférence, des valences fonctionnelles hydroxy, sont destinées à être utilisées comme matrices pour la spectrométrie de masse à désorption/ionisation assistée par matrice. Les échantillons sont généralement refroidis dans le spectromètre de masse jusqu'à ce qu'ils atteignent des températures bien inférieures à la température de la pièce.
