    Abstract: A system and method for performing automated titrations. An automatic titrator utilizes control devices and sensors adapted for various chemical reactions to perform titrations and determine the content of a desired component of a solution. Batch and continuous mode titrations are possible. Titrant is added to a sample either in varying amounts or rates and a titration endpoint is observed via sensors. Control devices detect when the titration endpoint occurs and calculates the desired content. Various reactions within the solution may be suppressed in order to titrate isolated components individually.

    Abstract: A method of detecting concentration of dipicolinic acid and terbium chloride in a chemical composition with a fluorometer, wherein the fluorometer comprises an excitation source for emitting electromagnetic radiation at one or more wavelengths, and a detector module for detecting fluorescence emitted by dipicolinic acid, emitting electromagnetic radiation from the excitation source at wavelengths that induce fluorescence in dipicolinic acid-terbium chloride combination present in the chemical composition, detecting the fluorescence emitted by the dipicolinic acid-terbium chloride combination via the detector module, and determining the concentration of dipicolinic acid using predetermined relationship between fluorescence emitted and the concentration of dipicolinic acid-terbium chloride combination.

    Abstract: A fluorometer for measuring fluorescence of a sample includes an excitation source for emitting electromagnetic radiation along a first beam path to induce fluorescence in the sample. An excitation filter transmits electromagnetic radiation from the excitation source toward the sample. An excitation filter holder supports the excitation filter and defines an aperture for passage of electromagnetic radiation from the excitation source. The aperture is positioned asymmetrically relative to the first beam path such that the aperture allows an asymmetrical portion of the electromagnetic radiation in the first beam path to pass toward the sample and the excitation filter holder blocks passage of a corresponding asymmetrical portion of the electromagnetic radiation in the first beam path. The blocked passage of the corresponding asymmetrical portion of the electromagnetic radiation in the first beam path reduces the amount of electromagnetic radiation oriented directly from the emitter module to the detector module.

    Abstract: Systems for quantifying one or more target analyte concentrations in a process solution are provided and can be used, for example, in methods for quantifying a target analyte concentration. These systems and methods include continuous and batchwise automated titration methods that use titration chemistries to measure the target analyte concentration in the process solution using a multiwavelength detector. The methods provide for efficient and robust automated titration methods for a variety of target analytes and can include methods that analyze more than one analyte and that provide for a dynamic range for measurement of more than one target analyte concentration.
