Der volle Inhalt der QuelleChemical sensors based on metallic oxide undergo a significant lack of selectivity to gases. To overcome this problem, we proposed a solution based on the electronic nose approach, i. E. The combination of several sensors with appropriate pattern recognition methods. A semi-automatic test bench including a matrix composed of several commercial gas sensors was carried out. We used two sensor heating procedures (isotherm mode and temperature modulation mode). Principal component analysis and artificial neural networks were used as pattern recognition techniques. The first heating procedure, applied to a six-sensor array, allowed to classify and to identify five toxic gases (CO, NH3, H2S, C2H2 and NO, each gas concentration was 100 ppm). Moreover, the quantification of gas in binary mixtures was satisfactory, with a RMSEPr value of about 10 %. The second heating procedure, applied to a four-sensor array, allowed to identify three reducing gases (CO, C2H2, and H2S) with concentrations varying from 25 ppm to 100 ppm

Der volle Inhalt der QuelleThe objective of this work was the development of an hydrogen fluoride (HF) sensor by mechanical response of SiOx and Si3N4 microcantilevers that have typical dimensions of 2003́00́. 5 æm. Their fabrication uses thin films coating, lithography and reactive ion etching processes. A XPS, SIMS, AFM study of the dielectric layers shows a lateral etching orientation for SiOx and a transversal one for Si3N4. A gold layer (not reactive) is deposited on one face of the cantilever, making it sensitive to both temperature and surface stress. The sensitivity of the system to the temperature, pressure and humidity has been defined. SiOx and Si3N4 layers reactivity toward HF was measured in term of deflection and frequency resonance variation. The response of the sensor depends on the amount of HF introduced into the cell. The gas is then detected in term of irreversible deflection until 260 ppb. The influence of the surface roughness and stoichiometry of the reactive layers was demonstrated

Der volle Inhalt der QuelleThe gas sensors based on metallic oxides carried out on substrates of silicon present the majority of the devices of gas detection available in the Irade. The major problem encountered by these sensors, is often, the lack of selectivity, reproducibility, and the low sensitivity. In this work we realized, by using the micro-electronics techniques, a microsensor based on WO3 for the ozone detection. The sensor consists of two intergidited electrodes of platinum and of a thin layer of WO 3 (~ 60nm) deposited on SiO 2 / Si by R. F. Magnetron reactivate sputtering. This technique allows controlling the morphology of deposited layers- We studied the influence of several parameters. The self biasing voltage, acts more particularly on the density of me deposited layers. The percentage of oxygen present in plasma during the deposit affects primarily the size of the grains, the deposit time acts linearly on the layer thickness, in the studied range. The correlation between the sensitive layer morphology and the sensor response to ozone, enabled us to determine the realization process of a sensor which presents : a good response to ozone (R ozone / R air = 335), in a reproducible and stable way. We found that a homogeneous, granulose morphology with a small grains (~ 60nm), and a large specific surface is adapted for the gas sensor application. This morphology was obtained for layers deposited during 10 min with a self biasing voltage equal to -200 V, and an oxygen-argon ratio equal to 1. We also studied the influence of the operating temperature on the sensors responses to ozone. This temperature plays a very significant role for the activation of the adsorption and desorption phenomena. The produced sensors present optimal responses for an operating temperature equal to 250 °C, lower than those described in the literature

Der volle Inhalt der QuelleThe intelligent gas sensor array systems (electronic nose) present an increasing development in many fields of applications. Concerning the campaign against the atmospheric pollution, the principally aim of our work is to realize and to validate a portable and autonomous electronic nose. After a state of the art on real time measurement of pollutant gases and the presentation of the principle of an electronic nose, a nomination of requirements for the engineering of a prototype is indicated. In order to fulfil the criteria of flexibility, cheapness, robustness and portability, we justify the choice of the six metal oxide gas sensors and the intelligent unit (microcontroller and Compact Flash memory) as well as the other components and their assembly. The realized prototype has been validated in laboratory for the detection of three pollutants gases: H2S, NO2 and SO2 in isolated state or in various mixtures with the small concentrations of industrial pollution near of emission sources. We have chosen multiple representative parameters of different phases and variations of the response of all the sensors. These parameters constitute a learning base and they are explored by a supervised classification method (Discriminant Factorial Analysis). We obtain a very good classification of the studied gas atmospheres as well as the concentrations of each atmospheric component. The obtained decision rules, which have been established in the memory of the prototype, allow the successfully identification of unknown gas composition samples

Der volle Inhalt der QuelleTHe dioxide of cerium is used as gas sensor. Twos systems based on oxides of Ce(+IV) and of Nd(+III) are studied : a multiphase and nonostructured system, obtained by soft chemistry, at low temperature, starting from oxalates and of acetates ; a ceramics with micrometric granulometry, obtained after sintering of the nanostructured powders, to 1600°C. The structures are elucidated by DRX. Morphology is chacterized by MET coupled with the EDAX. The electric properties according to the composition in the temperature range 40-700°C are measured by SIE. With the top of 400°C, the contributions of the bulks grain boundaries and electodes are separate. Eponent n of model CPE is related to the microstructure. Conductivity reaches a maximum with neodymium 10%. The catalytic properties are studied for air-methane mixtures by spectroscopy IRTF. Measurements of conversion of methane show that these catalysts are very active at 350°C

Der volle Inhalt der QuelleOne of the major challenges in the modern era is how we can detect the disease when we are still feeling healthy via noninvasive methods. Exhaled breath analysis is offering a simple and noninvasive tool for early diagnosis of diseases. Molecularly modified SnO2 sensors seem to be promising devices for sensing polar gases such as ammonia. SnO2 surface functionalization was performed in order to obtain sensitive and selective ammonia gas sensor that operates at room temperature. The first step of functionalization is the covalently attachment of 3-aminopropyltriethoxysilane (APTES) film on SnO2 in vapor or liquid phases. The characterization performed by the Infrared Spectroscopy and X-ray Photoelectron Spectroscopy, show that more APTES were grafted by hydrous liquid phase silanization. The second step was the functionalization of APTES modified SnO2 with molecules having acyl chloride of end functional groups molecules such as alkyl, acid and ester groups. Pure SnO2 and APTES modified SnO2 sensors did not show any significant sensitivity to ammonia (0.2-100 ppm) at 25 °C. On the contrary, acid and ester modified sensors are sensitive to ammonia between 0.2 and 10 ppm at room temperature. However, ester modified SnO2 was more selective than acid modified sensor regarding the ethanol and carbon monoxide gases. Ammonia variates the attached molecular layer’s dipole moment which leads to change in SnO2 conductance. Working at ambient temperature is also one of the advantages of these sensors in addition to the selectivity to ammonia regarding other gases such as ethanol, carbon monoxide and acetone

Der volle Inhalt der QuelleThe odor perceived in the vicinity of industrial areas is often the result of a combination of several odor sources. The objective of this thesis is to quantify simultaneously the contribution of each of these sources to the overall nuisance, in order to take appropriate corrective actions. In order to do so, two approaches are studied: the measurement of gaseous effluents using an electronic nose containing 6 non-specific gas sensors, and the chemical analysis of Volatile Organic Compounds (VOCs) in the gaseous effluent using chromatographic techniques. The innovative aspect of the thesis comes particularly from the data analysis used in the two methods:- For the electronic nose, the signals obtained from the measurements of mixtures of odor sources are interpreted by calculating their proximity to the signals obtained from the measurement of individual sources: the proximity of a source can be correlated with its portion in the sample.- The use of a receptor model (the "Chemical Mass Balance", or “CMB” model) allows to interpret the concentrations of VOC in a mixture of sources. Indeed, each source having its own unique signature (or pattern), by performing different linear combinations of sources, it is possible to fit these combinations to the pattern of the mixture
