1. A system for the solid phase synthesis of multiple species of organic compounds each formed by repeated synthetic cycles of synthetic steps, said system comprising:
- a computer for processing a program of instructions correlated to predetermined synthetic cycles for the synthesis of each of said multiple species;
an automated robot responsive to said computer, said automated robot operative to cause said synthetic steps to be performed in accordance with the synthetic cycles of each of said multiple species; and
a timing protocol, implemented by said program of instructions and executed by said computer, for directing synthetic steps of at least two different species to be performed concurrently, said timing protocol determining if the time for a synthetic step in the synthetic cycle of one of said at least two different species is sufficient for initiating a synthetic step in the synthetic cycle of another of said at least two different species.

Abstract
A solid phase synthesis system is provided by employing a fully automated robot that operates with a novel timing protocol for handling multiple synthetic tasks efficiently. The novel timing protocol is realized by performing steps in the synthesis cycles for different compounds, such as peptides, concurrently rather than on a sequential basis.
