Abstract: A liquid sample (104) introduced in a main flow passage (101) is held in a dam portion (105), and a trigger liquid (106) is filled in a trigger flow passage (102). In this state, the trigger liquid (106) is further introduced at desired timing into the trigger flow passage (102) so that the front end portion of the level of the trigger liquid (106) is advanced and the front end portion is brought to be into contact with the dam portion (105).

Abstract: Water is supplied to a water user outlet facility by maintaining a tappable flow of water in a recirculating loop that includes a pump such as a centrifugal pump driven by a substantially constant speed motor to establish the flow, a water delivery path that extends from the pump to the outlet facility, and a water return path that extends from the outlet facility back to the pump. The flow is permitted to be controllably tapped at the facility by a water user while directing any untapped portion of the flow into the water return path. Such recirculation avoids stagnation and thereby impedes deterioration in the potability of the water. Further such recirculation makes the recirculating loop and water within the loop less sensitive to the temperature of the surrounding environment. The recirculating loop may include a water purifier such as an ultra-violet lamp source to kill organic contaminants and, as well, may include a filter to remove inorganic material.
