Patent
CA 2401722
A method and an apparatus for selectively transmitting ions produced by a laser-based ionization technique is disclosed. The method relies on a FAIMS analyzer having a surface disposed therein for receiving a sample on the surface. The surface is in optical communication with a light transmissive port through which the laser light is directed such that it impinges upon the sample and causes ioniztaion thereof.
L'invention concerne un procédé et un appareil pour l'émission sélective d'ions produits par une technique d'ionisation à laser. Ledit procédé est mis en oeuvre au moyen d'un analyseur de spectrométrie de mobilité ionique à forme d'onde asymétrique à champ élevé, contenant une surface destinée à recevoir un échantillon. Ladite surface est en communication optique avec un port laissant passer la lumière, dans lequel la lumière laser est dirigée, de sorte qu'elle tombe sur l'échantillon et induise l'ionisation de celui-ci.
