An agitator (1) is for a liquid analysis system (3, 50). It has a chamber (5) for reception of a sample liquid. A passageway (6) from the bottom of the chamber (5) ends in an agitator chamber (7). A side wall of the agitator chamber (7) is formed by a diaphragm (8). The diaphragm (8) is connected to an electric motor (9) with an eccentric drive for reciprocating movement of the diaphragm (8). A gas inlet (10) in the opposite side of the body (2) is connected by a passageway (11) to the agitator chamber (7). The agitation chamber has a domed internal face opposed to the diaphragm, by which about 10% of the agitation chamber (7) volume is displaced by the inward movement of the diaphragm (8). Also, advantageously, there is a uniform application of displacement force within the agitation chamber (7) by virtue of the domed internal surface.

(canceled)
A liquid analyzer comprising an agitator, a gas supply, a liquid supply for a base or an acid solution, and an analyzer component for analysis of gas drawn from above liquid or of liquid in the analyzer, wherein the agitator comprises:
(canceled)
A method of mixing a gas with a liquid, the method being performed by an agitator, the method including drawing liquid from a sample liquid chamber through a liquid passageway, adding gas to the liquid in an agitation chamber and in an end of the liquid passageway, and then forcing the liquid and gas through the liquid passageway into the sample liquid chamber, thus promoting mixing of the gas with the liquid as it is compressed in the agitation chamber and forced back through the liquid passageway into the liquid sample chamber,
