Abstract: Systems, methods, and sampling probes for chemically testing a liquid sample are provided. In accordance with one embodiment of the present disclosure, a system generally includes a sample container for containing a liquid, wherein the liquid includes a chemical compound of interest and a reducing agent, and a non-corrosive sampling probe comprising a first channel for delivering a flow of gas to the liquid sample, and a second channel for purging sample fluid from the sample container, wherein at least a portion of the sampling probe is in contact with the liquid.

Abstract: In accordance with one embodiment of the present disclosure, a method for processing a liquid test sample includes using a needle assembly to introduce a first flow of gas through an inlet in the needle assembly into a container containing a liquid test sample and to provide an outlet from the container through the needle assembly, separating at least one volatile component from the sample in a gas and liquid separator using the first flow of gas, adsorbing the at least one volatile component onto a trapping material to provide at least one adsorbed component, and releasing the at least one adsorbed component from the trapping material to provide at least one released component.

Abstract: Automated systems and methods for processing liquid test samples are generally provided. Automated systems generally include a gas and liquid separator configured for removing at least one volatile component from the test sample, a first trapping vessel in fluid communication with the gas and liquid separator, wherein the first trapping vessel contains a trapping material capable of adsorbing at least one of the at least one volatile component to provide at least one adsorbed component, and a heat source configured to heat the trapping material to a temperature sufficient to release at least one of the at least one adsorbed component from the trapping material to provide at least one released component.

Abstract: A spectrophotometer system includes an optics block housing an excitation lamp and a cell for receiving a gas to be detected. The excitation lamp excites atoms of the gas to be detected to produce photons. The spectrophotometer system also includes a photo-multiplier tube assembly and an analog-to-digital converter. The photo-multiplier tube assembly detects the photons, and produces an analog output accordingly. The analog-to-digital converter converts this analog output to a digital output. The photo-multiplier tube assembly and the analog-to-digital converter of a spectrophotometer system are calibrated together so that a zero input to the analog-to-digital converter may be defined as an absence of photons. The optics block is configured to minimize scattering of light, without a lens, so that the output of the spectrophotometer system is a function of the number of atoms of the gas to be detected and not of scattered light.
