  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Results of the Application of a New Laser Based Open-Path Spectrometer for the Measurement of Fugitive Emissions From Gas Processing Plants

    Abstract In this paper, we present results from field studies of the application of a new laser based spectrometer incorporated with real-time dispersion modeling techniques to measure fugitive emissions from gas processing facilities. While open-path FTIR spectrometers can measure a variety of gaseous species, they suffer from the drawbacks of being large, expensive and of limited range. Also, ...

  • Sorption of lead from aqueous solutions by tea wastes

    Received for publication March 27, 2009. Environmental contamination by heavy metals has long been a worldwide concern. Tea wastes, having porous surfaces with polar functional groups, could be a good sorbent for removal of Pb(II) from wastewaters. This study aimed to investigate the potential of tea wastes as a sorbent for removal of Pb(II) from solution and the underlying sorption mechanism. ...

  • Synthesis of carboxyl-introduced chitosan with C2 amine groups protected and its use in copper (II) removal

    A route for the formation of carboxyl-introduced chitosan (CI-CS) with C2 amine groups protected (CIAP-CS) was investigated to improve copper (II) adsorption. First, the C2 amine groups of the chitosan (CS) were protected via a Schiff-base reaction by benzaldehyde. Then the product was obtained by the introduction of pyromellitic dianhydride to the C6 hydroxyl groups on CS via ...

  • Comparison of field and laboratory collected midwave and longwave infrared emissivity spectra / data reduction techniques

    Abstract Many targets that remote sensing scientists encounter when conducting their research experiments do not lend themselves to laboratory measurement of their surface optical properties. Removal of these targets from the field can change their biotic condition, disturb the surface composition, and change the moisture content of the sample. These parameters, as well as numerous others, ...

  • Optical couplers: key hardware for high quality FTIR spectroscopy

    Description Optical couplers are used to take the light coming from the source of a FTIR and route it through the sampling accessory and into the FTIR detector. This is an essential process in the effective use of the FTIR spectrometer. Therefore, optical couplers play an essential role in the proper use and maintenance of a FTIR system. Recognizing the importance of optical couplers ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • Measurement of moisture in HBr

    Introduction Moisture in corrosive gases will accelerate the rate of metal corrosion in gas supply systems which, in turn, can lead to their premature failure. For this reason, it is important to monitor moisture levels in these gases. FTIR is an effective way to monitor for moisture in these corrosive gases. In order to determine low levels of moisture in corrosive gases, it is ...

  • Leak detection in semiconductor fab gas processes

    Problem Statement Often times in semiconductor fabs moisture levels are monitored to ensure that products aren’t damaged by excess moisture in the process. If there are above normal levels of moisture, pinpointing the source of that moisture can be difficult. The moisture could be evolving from impurities in gas tanks or leaks in the sampling lines. One way to avoid downtime ...
