Criteria gases, VOCs, Acids and Organics pre- sent refineries with a challenging list of compounds to monitor. The Cerex AirSentry FTIR adds significant capability to our UV Sentry to simplify 1180 and 12-15 compliance with a minimum of hardware and a single software and integration platform. Both the AirSentry FTIR and UV Sentry ...
EPA Criteria for OP UVDOAS Sub PPB Detection Limits for Benzene Insitu, Traceable QA Audit at Full Path with Ambient Interferent Gases Present Time Resolved Monitoring Real Time MDL Output as DQI Real Time Signal Intensity Output as DQI Retention of Raw Spectral Data Importance of EPA Criteria EPA criteria for UVDOAS has deep roots in TO- 16 and applies to both UVDOAS ...
Characteristics of the adsorbent were also studied using scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR). It was revealed from kinetic tests that removal efficiency of MB was 88.5% under the optimum conditions of pH 8, initial MB concentration of 50 mg/L, contact time of 60 min, and adsorbent dose of 0.3 g/L. The oxygen functional groups such as ...
“In addition to the GHG/sustainability measure, the emissions data from the FTIR analyser also helps us to better understand the carbon and nitrogen cycles within the cropping systems.” The Gasmet DX4030 employs an FTIR spectrometer to obtain infrared spectra from each gas sample by first collecting an ‘interferogram’ of ...

The TGA/IR comparison in Table 1 was done on a single wavelength fixed filter analyzer, the Inf raCal Soot Meter (see photo). Table 2 shows comparative data for an FTIR and fixed filter IR. The comparisons show that both FTIR and filter based IR analyzers can replaceTGAfor measuring soot levels. Having access to a full spectrum gives an ...
The IRGAS-EPI/Hx is optimal for moisture in ammonia analysis because of the combination of a FTIR spectrometer that utilizes a TE-Cooled InAs detector and a long path gas cell. ...
Furthermore, measurement of gas concentrations at different depths enabled direct comparison with soil analysis. Using FTIR in the 'field' The Gasmet DX4015 is a portable FTIR gas analyser for ambient air analysis. ...
The surface modification of DEDMA-sepiolite was examined by the FTIR technique. The experimental data fitted very well with the pseudo-second-order kinetic model with the correlation coefficients above 0.985. The Langmuir, Freundlich and Dubinin-Radushkevich (D-R) adsorption isotherm models agree well with experimental data. The Langmuir-isotherm ...
