Disclosed is an organic carbon detector that can be used with a liquid chromatography equipment such as a size exclusion chromatography. The organic carbon detector contains a carbon oxidization subsystem and a stripping and CO.sub.2 detection subsystem arranged and detachably connected with each other in said order. The carbon oxidization subsystem contains a microfluidic agent injection module (1), an inorganic carbon removal module (2), a microfluidic ultraviolet oxidation module (3) and a vacuum pumping system (4), configured to remove inorganic carbons and oxidize organic carbons. The stripping and CO.sub.2 detection subsystem contains a stripping module (7) and a CO.sub.2 detector (12), using a carrier gas to transfer the organic carbon converted gas to the CO.sub.2 detector (12). Also disclosed is a method of using the organic carbon detector in water quality monitoring.

An analysis device having a liquid chromatograph prevents a plurality of streams from being unusable at the same time Whether a usable stream is 0 or not among streams 1, 2, and 3 is determined. In a case where none of the streams is usable, the control unit skips a sample introduction in the cycle; and where there is one usable stream in the cycle, the stream is used. In a case where there are multiple streams that are usable in the cycle, and there are multiple streams of which the remaining number of uses of a separation column is the minimum, the stream having the smallest stream number is used; and where there is one stream of which the remaining number of uses of a separation column is the minimum, the stream to which the separation column having the minimum remaining number of uses is connected and used.
