A true chemical clock: Serially coupled chlorite–iodide oscillators

A set of serially coupled flow reactors are modeled which contain chlorite–iodide oscillators. By independently varying the reactor flow rates it is possible to produce oscillatory systems with differing periods where the ratio of the period of oscillation between reactors is always an integer value. This system was thoroughly examined and utilized to produce a ‘true’ chemical clock whose three reactors oscillate with a frequency of minutes, hours, and days.
