Ionization Mechanism of Matrix-Assisted Laser Desorption .

In past studies, mistakes in determining the ionization mechanism in matrix-assisted laser desorption/ionization (MALDI) were made because an inappropriate ion-to-neutral ratio was used. The ion-to-neutral ratio of the analyte differs substantially from that of the matrix in MALDI. However, these ratios were not carefully distinguished in previous studies. We begin by describing the properties .

The UV dose can be determined in a batch system by multiplying the calculated average intensity by the specific exposure time. When using polychromatic light sources (e.g., medium-pressure lamps), UV dose calculations in batch, bench scale experiments also incorporate the same parameters as a low- pressure lamp collimated beam test.
