Patent ID: 7987701

Claim:
A method of analyzing drinking water samples comprising the steps of: a) providing at least one stream of drinking water that has been disinfected with chlorinated or chloraminated materials; b) transporting said at least one stream of drinking water through a capillary membrane sampling device such that all volatile trihalomethane compounds present within said drinking water stream separates from said stream within said capillary membrane sampling device into a stream of reagent water, and wherein any haloacetic acid compounds remain within said at least one stream of drinking water; c) transporting both of said trihalomethane-containing stream of reagent water and said drinking water haloacetic acid-containing stream to a ten-port valve, wherein said valve is configured to inject only one of said trihalomethane-containing stream or said haloacetic acid-containing stream to a mixing manifold at a time, wherein when one of said streams is injected into said mixing manifold, the other stream loads into a sample loop, and wherein said valve alternates from injection to load positions for both streams by action of an actuator; d) mixing either of said streams with a fluorescing compound within said mixing manifold to form a fluorescing stream therein; and e) transporting the fluorescing stream to a fluorescing detector to determine the amount of each compound within each stream through fluorescence detection.
