Patent

CA 2502919

Methods and apparatuses for the high-energy desorption/ionization of various compositions are disclosed. The methods and apparatuses of the invention generally utilize structured substrates, such as micro- and nano-structured films, optionally in combination with one or more surface coatings, to provide enhanced desorption of analytes. Such enhanced desorption is particularly useful in fields of analysis such as mass spectroscopy which use laser desorption of the substrate.

L'invention porte sur des procédés et des appareils assurant la désorption/ionisation à haute énergie de différentes combinaisons, et utilisant généralement des substrats structurés tels que des films micro ou nanostructurés facultativement combinés à un ou plusieurs revêtements de surface permettant d'accroître la désorption d'analytes, cette désorption accrue étant particulièrement utile dans des domaines d'analyse tels que la spectroscopie de masse à désorption au laser d'un substrat.
