Abstract: The proposed method is related to the field of technical physics, in particular, to spectral methods for determining the elemental composition of liquid media using an electric discharge in the liquid as a source of spectra. The method can be implemented in devices for determining elemental composition of liquid media. The areas of application include water treatment systems at public water supply facilities, nuclear and thermal power industries, chemical industry, food industry processes (for water quality control), environment monitoring, etc.
The technical result of the invention is a higher stability and reproducibility of measurement results and a better long-term operation reliability of the device.
The proposed method for emission analysis of elemental composition of liquid media includes initiation of a local electric discharge in the liquid under analysis with the formation of a current-carrying channel in the volume of a diaphragm opening made in a member of the electrolytic cell structure, and detection of the generated emission spectra of the chemical elements being determined.
The result is obtained due to the fact that the elements being determined are first deposited in the current-conducting channel volume at a current insufficient for initiating a local electric discharge, then the current direction is changed and its magnitude is increased for initiating a local electric discharge, and the emission generated in the liquid being analyzed is detected as emission spectra of the elements being determined.
The deposition current intensity can be selected according to elements to be determined and their concentration in the liquid.Abstract translation: 所提出的方法与技术物理学领域有关，特别是涉及使用液体中的放电作为光谱来确定液体介质的元素组成的光谱方法。 该方法可以在用于确定液体介质的元素组成的装置中实现。 应用领域包括公共供水设施，核电，热电行业，化工，食品工业（水质控制），环境监测等水处理系统。本发明的技术成果具有较高的稳定性和重复性 的测量结果和更好的长期运行可靠性的设备。 所提出的液体介质的元素组成的排放分析方法包括在分析中的液体中开始局部放电，在电解池结构的构件中形成的隔膜开口的体积中形成载流通道， 并检测所确定的化学元素的产生的发射光谱。 结果是由于以下事实获得的：首先将所确定的元件以不足以引发局部放电的电流沉积在导流通道体积中，然后改变电流方向并且增加其幅度以引发局部电 检测在被分析液体中产生的发射作为所确定的元件的发射光谱。 沉积电流强度可以根据要确定的元素和它们在液体中的浓度来选择。

Abstract: An analysis apparatus includes a plasma generation unit and an optical analysis unit. The plasma generation unit generates initial plasma by momentarily energizing a target substance to be turned into a plasma state, and maintains the target substance in the plasma state by irradiating the initial plasma with an electromagnetic wave for a predetermined period of time. The optical analysis unit identifies the target substance based on information with respect to emission intensity during a period from when the emission intensity reaches a peak due to the initial plasma until when the emission intensity increases and reaches approximately a constant value due to electromagnetic wave plasma maintained by the electromagnetic wave, or information with respect to emission intensity after the electromagnetic wave irradiation is terminated.

Abstract: Multiple energy sources, such as a laser and electrical field, are employed, in close coordination, spatially and temporally, to clean a sample, vaporize its material and excite vapor atoms for the purpose of atomic emission spectroscopy. These methods permit better monitoring and control of the individual processes in real time, lead to higher consistency and higher quality optical emission spectra, and enhance the measurements of non-conducting solids, liquids and gases. Additionally, a portable instrument is provided with both laser source and spectrometer optically coupled to a hand-holdable unit.

Abstract: A hand-held, self-contained, battery-powered test instrument for analyzing composition of a sample includes an exciter for exciting at least a portion of the sample, a compact cross-dispersed spectrometer for receiving an optical signal from the excited portion of the sample and a processor for processing spectral data about the optical signal from the spectrometer. The exciter may include a spark generator and a counter electrode, a laser or other device for generating the optical signal from the sample portion. The spectrometer has a wavelength range broad enough to enable the test instrument to detect and determine relative quantities of carbon, phosphorous, sulfur, manganese, silicon, iron and other elements necessary to identify common alloys. The spectrometer includes a structural member made of a light-weight material having a small coefficient of thermal expansion (CTE). The spectrometer is dimensionally stable over a range of expected ambient temperatures, without controlling the temperature of the spectrometer.
