Patent

CA 2588327

An analyte for atomic spectrometry detection is prepared by introducing an aerosol of the analyte into a chamber, and irradiating the aerosol with ultraviolet light in the presence of a low molecular weight organic acid or other suitable photoactivatable ligand donor species to create vapor containing the analyte. The vapor containing the analyte is extracted from the chamber and used for atomic spectrometry detection.

La présente invention concerne la préparation d~une substance à analyser pour une détection par spectrométrie atomique qu~on obtient en introduisant un aérosol de la substance à analyser dans une chambre et en irradiant l~aérosol à l~aide d~une lumière ultraviolette en présence d~un acide organique de faible masse moléculaire ou de toute autre espèce donneur de ligand photoactivable pour créer une vapeur qui comprend la substance à analyser. La vapeur comprenant la substance à analyser est extraite de la chambre et utilisée pour une détection par spectrométrie atomique.
