CORRELATING SPECTRAL POSITION OF CHEMICAL SPECIES ON A SUBSTRATE WITH MOLECULAR WEIGHT, STRUCTURE AND CHEMICAL REACTIVITY

摘要

System and method for printing chemicals in an array includes a delivery channel (20) with aperture (22) moveable relative to substrate (26) by precision controller (28) coupled to sensor (40). Chemicals may be supplied from a separation device (14), such as a chromatographic separator, and identified by an analyzer (33).
