Provided are a method and an apparatus that enable rapid and automatic determination of the coagulant injection rate in a process of water treatment through coagulation and sedimentation. Using a coagulation analyzer comprising sample tanks 1A to 1D each for keeping a predetermined amount of raw water, a water supply pump 7, water supply/discharge valves 4, 6 for raw water and washing water, mixers 3A to 3D, a coagulant injection unit 21, and a detector 30 for determining the particle size and the particle number of flocs, the time within which the coagulant 20 injected into the sample tanks is dispersed by mixing and the particles begin to agglomerate (agglomeration start time) is determined, and based on the thus-determined agglomeration start time, the coagulant injection rate is determined, or the amount of the coagulant to be injected is controlled.

An apparatus for quantitative determination of trihalomethanes comprises a separation unit containing two channels in contact with each other via a microporous membrane that will not react with trihalomethanes, a reaction unit for heating a carrier solution that has passed through the separation unit, a cooling unit for cooling the carrier solution that has undergone complete reaction; and a detection unit for determining the quantity of a fluorescent substance in the carrier solution. A method for quantitative determination of trihalomethanes comprises flowing a sample solution or a mixture thereof with a reducing agent through one of the two channels in the separation unit, flowing the carrier solution through the other channel, heating the carrier solution that has passed through the separation unit and to which an alkaline nicotinamide or a derivative thereof has been added, cooling the carrier solution, and subjecting the cooled solution to fluorimetry.

In an imaging apparatus, an erroneous shake correction is prevented from being performed due to a front curtain shock. A shutter selecting section determines a current state is a shake-correction execution mode when a shake correction switch is ON, when a tripod detection sensor tripod is not mounted, when a shake detection sensor senses a shake amount equal to or larger than a predetermined value, and when a shutter speed is lower than a predetermined value. In this case, the shutter selecting section selects an electronic focal plane shutter as the front curtain, and supplies an operation command signal to an electronic focal plane shutter control section. In other cases, the shutter selecting section determines the current state is not the shake-correction execution mode, and selects a mechanical focal plane shutter as the front curtain and supplies an operation command signal to a shutter drive control section.
