Abstract:

The presented work shows the necessity of organization of individual instrumental control of the content of rocket fuel and its products in the air of rocket-space industry enterprises. No accurate analysis of gas analyzers presented on the Russian market, providing individual instrumental control of concentrations of heptyl and its derivatives in the workplace air is available. Therefore, the task of express, automatic, selective and simultaneous monitoring of heptyl vapors and derivatives of its transformation in the air of industrial premises by one instrument and replacing the imported gas

Abstract:

The article presents the results of the development of a universal calibration technique for measuring the content of components in gaseous media. The technique can be applied both for the simplest non-automatic gas analyzers (manual) and for automatic ones with their own software, and also allows the user to adjust the device parameters to certain environmental conditions. An algorithm for calibrating gas analyzers has been compiled, and the process of evaluating measurement results has been described. The proposed technique has been tested on ANCAT-7664 Micro gas analyzers of various models

The lack of automatic control is a drawback of mine interferometric analyzers of methane and carbon digestion concentration in air. We present the results of developing an algorithm for automating the process of measuring the concentration of methane and carbon dioxide in air with a mine interferometric analyzer. An automatic determination of the shift of the interference pattern by the gas under study is proposed using an opto-electronic device.

Environmental monitoring is one of the key elements to ensure the most effective security measures in various areas of life. The most famous technology in this field is the gas detection system within the framework of atmospheric air monitoring. It serves not only for an early warning program, but also for a constant check of the state of the atmosphere in certain areas. In the guidelines of the World Health Organization (WHO), updated in 2005, solid particles (dust or suspended substances) are among the main indicators of atmospheric air quality.

Micrometeorological methods to quantify fluxes of atmospheric constituents are key to understanding and managing the impact of land surface sources and sinks on air quality and atmospheric composition. Important greenhouse gases are water vapor, carbon dioxide, methane, and nitrous oxide. Further important atmospheric constituents are aerosols, which impact air quality and cloud formation, and volatile organic compounds. Many atmospheric constituents therefore critically affect the health of ecosystems and humans, as well as climate. The micrometeorological eddy covariance (EC) metho

Introduction. The importance of fire safety (FS) measures at fuel and energy industry facilities, in particular over the course of continuous technological processes of oil refineries (OR), is highlighted in the article. Decision makers are able to manage the process of planning and implementing these measures thanks to special software integrated into automated process control systems. The fire and explosion prevention subsystem designated for managing gas analyzing equipment and its control processes was chosen as the object of research. Theoretical framework.

Abstract:

Critical care medicine department has to assess electrolytes accurately and quickly to initiate the treatment. Blood samples are analyzed in a matter of seconds by arterial blood gas analyzers (ABG), albeit their accuracy is still up for debate. The current study objectives were to estimate and compare the levels of electrolytes (sodium, potassium, and chloride) in hospitalized critical care patients as determined by automated biochemistry analysis and blood gas analyzer and to assess the degree of agreement between the two instruments and obtain information on whether these values can be inte

Abstract:

In Groningen, all organic samples for accelerator mass spectrometry (AMS) are combusted in an automatic Elemental Analyzer, coupled to an Isotope Ratio Mass Spectrometer and Cryogenic Trapping System. The Gas Chromatographic (GC) column, part of the Elemental Analyzer system, appeared to be the main cause for memory effects. Therefore we modified the Elemental Analyzer, such that the trapped CO2 no longer passed the GC column. Our system modification reduced the memory effect significantly, as shown by lower radiocarbon concentration values for anthracite backgrounds, and a much smaller spread

Abstract:

For waterworks the most fundamental subject is to maintain the safety of drinking water. It has become important every year to monitor the concentrations of trihalomethanes (THM). We developed a new automatic THM analyzer based on fluorometry with membrane separation, and investigated a correlation between the gas Chromatographic method and our THM analyzing method on drinking waters at 10 cities in Japan. The investigation resulted in good correlation (r=0.9807) between both methods. Good results were obtained when continuous measurements of THM in drinking water were performed by the analyze

However, in portable devices, the results may be influenced by the analyzer’s technological approach, being either breath-by-breath (BBB) or dynamic micro mixing chamber mode (DMC). The portable metabolic analyzer K5 (COSMED, Rome, Italy) provides both technologies within one device, and the authors aimed to evaluate differences in between modes in endurance athletes.
