ON-SITE KIT FOR ANALYSIS OF DISINFECTANT BYPRODUCTS SPECIES AND AMOUNTS THEREOF IN DRINKING WATER SUPPLIES

摘要

The present invention relates to the provision of a portable kit that permits reliable and quantifiable analysis of trihaloamethanes and haloacetic acids within drinking water samples utilizing a hand-held (portable) fluorescing detection instrument for simultaneous measurements of such species. With the necessity to chlorinate drinking water to remove harmful bacteria and other potential toxins, trihalomethane and haloacetic acid byproducts are generated during such a disinfecting procedure that may harm humans after consumption as well due to highly suspect carcinogenicity. A reliable manner of measuring such drinking water supplies for such disinfectant byproduct levels is highly desirable, particularly through the utilization of a relatively inexpensive analytical instrument for such a purpose. The inventive kit-based analytical method of the invention has been found to be nearly as reliable as source measuring methods for the same purpose, providing a relatively quick measuring method that may be undertaken at any drinking water source location.

主权项

1. A portable kit for analyzing drinking water samples comprising:
a) a capillary membrane sampling module comprising: a capillary membrane sampling device, a 2-channel pump, and at least two volumetric flasks; b) a nicotinamide fluorescence chemistry module comprising: reagent supplies of nicotinamide and a base, and at least two vials for mixing said nicotinamide reagent and said base reagent with at least two different water stream samples; c) a fluorescence detector module comprising: a hand-held fluorescence detector and at least two cuvettes that may be introduced within said fluorescence detector; and d) an accessories module comprising: a covered water bath that may be heated to at least 80° C. and an ice bath, wherein both said baths can hold both volumetric flasks within said capillary membrane sampling module simultaneously, and a thermometer to monitor the temperature of both baths; wherein all of said modules are simultaneously portable and carried within a single properly configured and compartmented protective enclosure.
