Abstract

Appareil et méthode de régénération d'échantillons d'ions pour un spectromètre de masse. Les échantillons de la source sont chargés sur un support qui est chauffé au moyen d'un faisceau laser, ce qui désorbe l'échantillon sans ionisation. L'échantillon désorbé est porté par un gaz porteur dans un tube de transfert, à la sortie duquel il est ionisé par une décharge d'effluve ou par photo-ionisation. L'échantillon ionisé ainsi obtenu peut être analysé dans un spectromètre de masse ou être utilisé pour servir dans toute autre intention.
