Patent ID: 7556773

Claim:
An analyzer comprising: a. a reactor vessel; b. a sample pump for flowing a sample into the reactor vessel; c. a base pump connected to a base reservoir for flowing a liquid base to the reactor vessel; d. an ozone generator adapted to create ozone and flow the ozone to the reactor vessel; e. an acid pump connected to an acid reservoir for flowing a liquid acid to the reactor vessel; f. a sampling valve connected to the sample pump, the acid pump, and the base pump for selectively flowing the sample, the liquid base, the liquid acid, or combinations thereof, into the reactor vessel; g. a circulation pump connected to the reactor vessel for mixing the sample, the liquid acid, the liquid base, and the ozone to oxidize at least a portion of the sample to its lowest state forming an oxidized liquid sample; h. a sample chamber for receiving the oxidized liquid sample in communication with the reactor vessel; i. an analysis pump in communication with the sample chamber for flowing the oxidized liquid sample from the reactor vessel to the sample chamber; j. a reagent pump for pumping reagent from a reagent source; k. a mixer for introducing reagent from the reagent pump to at least one of the oxidized liquid samples; l. a multicomponent detector comprising at least one measuring cell for receiving the oxidized liquid sample, measuring the oxidized liquid sample optically using a frequency of absorption of at least one component in the sample; and wherein the analysis pump is reversible for flowing oxidized liquid sample into the sample chamber upstream of the measuring cell after a measurement has been made; m. a cleaning pump connected to a cleaning fluid reservoir for flowing a cleaning fluid to the measuring cell; n. a flushing pump connected to a water supply for flowing water to the measuring cell after the cleaning fluid has flowed through the measuring cell; o. a cleaning fluid three way valve communicating between the cleaning pump, the measuring cell and the sample chamber; and p. a flushing valve communicating between the flushing pump, the measuring cell, and the sample chamber.
