A chemical synthesis apparatus (20) for building chemical compounds includes a head assembly (21) having an array of nozzles (22) with each nozzle or plurality of nozzles coupled to a reservoir (23) of liquid reagent (24), and a base assembly (25) having an array of reaction wells (26). A transport mechanism (27) aligns the reaction wells (26) and selected nozzles (22) in a longitudinal X-direction for deposition of liquid reagent (24) into selected reaction wells (26). A plurality of independently controllable sliders (100) move nozzle columns (41) in a lateral Y-direction for deposition of liquid reagent (24) into selected reaction wells (26). A first sliding seal (30) is positioned between the head assembly (21) and the base assembly (25) to form a common chamber (31) enclosing both the reaction well (26) and the nozzles (22) therein. A plurality of second sliding seals (120) is positioned between head assembly (21) and sliders (100). A gas inlet (70) into the common chamber (31), upstream from the nozzles (22), and a gas outlet (71) out of the common chamber (31), downstream from nozzles (22), sweeps the common chamber (31) of fumes emitted by the reagents.
