Standard protocols define the synthesis cycle for specific scales (10 micromole, 1 micromole, 2 micromole, 50 micromole) using repeated actions: injection, hold time, purge, manifold wash (ACN to waste followed by gas to waste), and optional mixed injections. Purge time is time-based due to a positive pressure system, and reverse purge can be enabled to purge top down, avoiding bubbling. Meta protocols chain standard cycles to run more complex syntheses across sequence positions, where the step order must remain consistent between parent and special protocols even though all parameters can change.
