- ПубликацияТолько метаданныеFast switching of the polarity of dual mode ion mobility spectrometer(2019) Pershenkov, V.; Belyakov, V.; Shaltaeva, Y.; Malkin, E.; Golovin, A.; Ivanov, I.; Vasilyev, V.; Matusko, M.; Gromov, E.; Беляков, Владимир Васильевич; Шалтаева, Юлия Ринатовна; Малкин, Евгений Константинович; Иванов, Игорь Александрович© 2019 IEEE.The ion mobility spectrometer with a fast switching of the polarity of the drift field is designed for alternate, incessant detection of positive and negative ions from nonradioactive active ionization source. It were also solved the problems of dielectric absorption on the collector and voltage stabilization on the protective ion grid.

A.; Belyakov, V. V.; Pershenkov, V. S.; Шалтаева, Юлия Ринатовна; Малкин, Евгений Константинович; Иванов, Игорь Александрович; Беляков, Владимир Васильевич© Springer Nature Switzerland AG 2020.The review considers the design of ion mobility spectrometers, which allow for the conditionally simultaneous detection of both positive and negative ions. The review of existing serial ion mobility spectrometers with simultaneous detection of substances in both spectrometric modes is carried out. The ways of realization of the bipolar ion mobility spectrometer are analyzed.
- ПубликацияТолько метаданныеThe algorithms modernization of temperature and gas control systems of ion mobility spectrometer(2020) Shaltaeva, Y. R.; Golovin, A. V.; Vasilyev, V. K.; Gromov, E. A.; Matusko, M. A.; Malkin, E. K.; Ivanov, I. A.; Belyakov, V. V.; Pershenkov, V. S.; Шалтаева, Юлия Ринатовна; Малкин, Евгений Константинович; Иванов, Игорь Александрович; Беляков, Владимир Васильевич© Springer Nature Switzerland AG 2020.New algorithms were developed to control the drift region heaters and the gas pumps of ion mobility spectrometer. The efficiency of substances detection was increased. Control algorithm block heaters can improve the accuracy of temperature stabilization in terms of the significant events of the time constants of thermal circuits and high heat capacity elements of the drift region. The improved control algorithm of a block of gas pumps minimizes the duration of the transition process when changing the predetermined level of the engine speed over a wide range. The study and optimization of control algorithms for heaters of the drift region and the gas pump ion mobility spectrometry.
- ПубликацияТолько метаданныеExhaled breath mass spectrometry in heart failure diagnostics(2019) Malinovskaya, L.; Bykova, A.; Chomakhidze, P.; Kopylov, F.; Patrikeev, L.; Vasilev, V.; Belyakov, V.; Golovin, A.; Pershenkov, V.; Malkin, E.; Gromov, E.; Ivanov, I.; Matusko, M.; Shaltaeva, Y.; Беляков, Владимир Васильевич; Малкин, Евгений Константинович; Иванов, Игорь Александрович; Шалтаева, Юлия РинатовнаCopyright © 2019 Inderscience Enterprises Ltd.Heart failure (HF) affects almost all organs and systems, including general and local pulmonary metabolism, thus effecting on volatile organic compounds concentration in expired air. The aim of the present study is to evaluate the value of expired air analysis (proton mass spectrometry, PTR-MS) for the diagnosis of HF. The study population included 19 patients with stable chronic New York Heart Association (NYHA) functional classification class 2-3 and 16 sex and age matched controls without signs and symptoms of HF. Expired air analysis could provide facilities of early diagnosis and monitoring in HF patients. Most patients had ischemic aetiology of HF, and 31% of them had NYHA class 2 and 69% NYHA class 3 symptoms. Fasted expired air collected by special Tedlar bags was analysed by Compact PTR-MS. The composition of expired air was analysed by deviation of the content of certain substances against their concentration in neutral air. Analysis of samples from patients reveals 24 substances that differ in concentration from the neutral air. Six of them differ significantly in patients with and without HF. Namely, the concentrations of acetone, formaldehyde, propylene, acetic acid, xylene and benzoates were significantly elevated in HF patients (p > 0.05).

The circuit design includes simulation of the dynamic formation of a sinusoidal signal. The simulation of the dynamic formation of a sinusoidal signal is investigated. It is characterized by a high voltage multiplier and several variants of a voltage smoothing filter.
- ПубликацияОткрытый доступThermal Conductivity Gas Sensors for High-Temperature Applications(2024) Samotaev, N.; Podlepetsky, B.; Mashinin, M.; Ivanov, I.; Obraztsov, I.; Oblov, K.; Dzhumaev, P.; Самотаев, Николай Николаевич; Подлепецкий, Борис Иванович; Машинин, Михаил Олегович; Иванов, Игорь Александрович; Образцов, Иван Сергеевич; Облов, Константин Юрьевич; Джумаев, Павел СергеевичThis paper describes a fast and flexible microfabrication method for thermal conductivity gas sensors useful in high-temperature applications. The key parts of the sensor, the microheater and the package, were fabricated from glass-coated platinum wire and the combination of laser micromilling (ablation) of already-sintered monolithic ceramic materials and thick-film screen-printing technologies. The final thermal conductivity gas sensor was fabricated in the form of a complete MEMS device in a metal ceramic package, which could be used as a compact miniaturized surface-mounted device for soldering to standard PCB. Functional test results of the manufactured sensor are presented, demonstrating their full suitability for gas sensing applications and indicating that the obtained parameters are at a level comparable to those of standard industrially produced sensors. The results of the design and optimization principles of applied methods are discussed with regard to possible wider applications in thermal gas sensor prototyping in the future. The advantage of the developed sensors is their ability to operate in air environments under high temperatures of 900 ‚шC and above. The sensor element material and package metallization were insensitive to oxidation compared with classical sensor-solution-based metalў??glass packages and silicone MEMS membranes, which exhibit mechanical stress at temperatures above 700 ‚шC.
