  • Method and apparatus for MALDI mass spectrometry
    Patent number: 5854486
    Abstract: A thin uniform film of matrix material is deposited from the gas phase on to a substrate for use in Matrix Assisted Laser Desorption and Ionization (MALDI) spectroscopy. The thin uniform film of material may be overcoated with another film of material which has a higher vapor pressure than the matrix material to prevent the matrix material from evaporating during storage and during substantial time in the vacuum environment of the mass spectrometer.
