[0135] Preparation of any processing solution sample for analysis may include adding or combining one or more reactants or reagents to the sample to form a mixture. A sample of this modified treatment solution is then analyzed by the method to determine the concentration of the active ingredient in order to ensure that the set point concentration is maintained. Accordingly, the method comprises obtaining, consisting essentially of, or consisting of a treatment solution sample having an unknown, initial concentration of one or more active ingredients to be determined.
[0136] Reactants and / or reagents can be added to the sample including the active ingredient simultaneously or sequentially. Mixing the reagents, reactants, and processing the solution sample results in a chemical reaction (eg, an electrochemical or chemiluminescent reaction) that generates a signal or readout. The chemical reaction of the method also converts the treatment solution sample into a modified treatm...
Embodiment 1
[0152] Example 1: Embodiment of the device of the present disclosure
[0153] Figure 1A is a schematic diagram showing various components of the device. As described in detail herein, the method or apparatus of the present invention comprises, consists essentially of, or consists of one or more of 1) Sampling and filtration system, such as one or more sample measuring cells; 2) Pump (e.g., high pressure pump); 3) Valve (e.g., jet valve or 6-port valve); 4) Column (e.g., chromatographic column) 5) one or more light sensing systems (e.g., detectors 1 and 2); 6) one or more dose injector systems; 7) one or more processing and / or mixing tanks; 8) delivery systems; 9 ) solution tank; 10) control system; and 11) reactants and / or reagents.
[0154] Additionally, FIGS. 1B-1I provide schematic diagrams of illustrative embodiments of one or more of each of the device components referenced in FIG. 1A . More specifically, images are shown of a prototype embodiment of components of the ...
Embodiment 2
[0155] Embodiment 2: the detection of the concentration of various fungicide active ingredients
[0156] This example relates to demonstrating the ability of the present method and apparatus to accurately detect the presence of active ingredients, such as biocides, in treatment solutions. 2A and 2B are schematic diagrams showing the basic processing steps and flow of the method. For example, Figure 3 demonstrates that multiple different fungicides were detected in a single treatment solution. This example further demonstrates that each active fungicide can be isolated and individually detected by HPLC. More specifically, the present method and device were able to separate and clearly detect the concentrations of the following active ingredients: fludioxonil (Fig. 4A), imazalil (Fig. 4B), o-phenylphenol (Fig. 4C), prochloraz (Fig. 4D), propiconazole (FIG. 4E), pyrimethanil (FIG. 4F), and thiabendazole (FIG. 4G).
[0157] Thus, this example demonstrates that each active bioci...
