Abstract
The invention provides methods for dispensing tools that can be employed to generate multi-element arrays of sample material on a substrate surface. The substrates surfaces can be flat or geometrically altered to include wells of receiving material. The tool can dispense a spot of fluid to a substrate surface by spraying the fluid from the pin, contacting the substrate surface or forming a drop that touches against the substrate surface. The tool can form an array of sample material by dispensing sample material in a series of steps, while moving the pin to different locations above the substrate surface to form the sample array. The invention then passes the prepared sample arrays to a plate assembly that disposes the sample arrays for analysis by mass spectrometry. To this end, a mass spectrometer is provided that generates a set of spectra signal which can be understood as indicative of the composition of the sample material under analysis.
