The paper discusses the concept of separation of quantum mechanical systemsin the algebraic approach. We review known theorems, then establish a linkbetween the C*-algebraic and the corresponding W*-algebraic concepts. Acharacterization of separation in terms of Bell inequalities, due to Raggio(1988), is given a C*-algebraic formulation. Finally, we comment on theimplications for the understanding of the Bell inequalities.
