Functionalized target support and method

摘要

The invention provides an apparatus that produces analyte ions for detection by a detector. The apparatus includes a matrix based ion source having a target substrate including an aromatic compound and a carbon nanotube material for producing analyte ions, an ion transport system adjacent to the matrix based ion source for transporting analyte ions from the matrix based ion source; and an ion detector downstream from the ion transport system for detecting the analyte ions. The invention also provides a method for producing and detecting the analyte ions.
