Abstract
An alignment plate is provided with a plurality of holes for guiding a pipette tip toward a sample plate of a MALDI mass spectrometer. Each of the holes is provided with a conical upper contour in order to guide the pipette tip toward a specific location on the sample plate. Two companion alignment plates are used in order to overlay two separate arrays of samples on the sample plate. For instance, a first of two alignment plates is formed with a 10×10 array of holes so that a 10×10 array of samples is deposited by the pipette tip onto the sample plate. The second of the two alignment plates is formed with a 9×9 array of holes so that a 9×9 array of samples is deposited on the sample plate at locations offset from the 10×10 array of samples already on the sample plate. The number of samples loaded on the sample plate is large and the space on the sample plate is more fully utilized.
