Unoccupied dosing unit connections (Ports) can be sealed with
drying tubes or stoppers.
• Divide your synthesis run into part steps and create separate XDOS
methods for the individual dosing steps. Then you can link together the
individual part steps (methods) to form a sequence (SEQ mode) and
add further commands to it.
