Abstract
VARIOUS types of compensator1–3 are used in electrophoresis to bring the initial boundaries into view, or to bring a particular boundary into the correct position for isolation of a sample. Manual control of the compensator is quite convenient in these cases. However, it is sometimes necessary to keep a boundary stationary during a long run, either for analytical purposes4, or in the course of preparative work5. The obvious type of automatic control is one based on a photoelectric device; but no such application seems to have been described in the literature.
