Presented here is the validation of the CrIS Fast Physical Retrieval (CFPR) NH3 column and profile measurements using ground-based Fourier Transform Infrared (FTIR) observations. We use the total columns and profiles from seven FTIR sites in the Network for the Detection of Atmospheric Composition Change (NDACC) to validate the satellite data products. The overall FTIR and CrIS total columns ha...

Two sets of experiments, categorized as TG–FTIR and Py–GC–FTIR, are employed to investigate the mechanism of the hemicellulose pyrolysis and the formation of main gaseous and bio-oil products. The ‘‘sharp mass loss stage’’ and the corresponding evolution of the volatile products are examined by the TG–FTIR graphs at the heating rate of 3–80 K/min. A pyrolysis unit, composed of fluidized bed rea...

Fourier transform infra red (FTIR) and energy band gap of potassium lithium borate glasses of different composition have been studied using Fourier FTIR and UV-VIS spectroscopy techniques. The glasses were melted in the alumina crucible in an electric furnace at 1100°C for 30 min until homogenous melt was obtained. The X-ray diffraction analysis was adopted for confirming the amorphous nature o...

In this paper we are presenting several expert systems built for the identification of illicit amphetamines using GC-FTIR spectra, GC-MS spectra and a hybrid GC-FTIR GC-MS spectral database (concatenated spectral database). The systems were built using Artificial Neural Networks (ANN), and are dedicated to the recognition of amphetamines. The database is formed by chemical compounds with toxico...

Like other optical spectroscopy methods, FTIR can provide accurate quantitative analysis for many analytes. With the proper calibration, FTIR spectra can yield both sensitive and selective determination. Although it was once common to post process data after collection, innovative software packages, such as Agilent MicroLab PC and Agilent MicroLab Mobile, provide direct reporting of quantitativ...

Binary and tertiary mixture of o~-tocophenol, cholesterol and dimyristoylphosphatidylcholine in the form of multilamellar liposomes were investigated by Fourier Transform Infrared and visible spectroscopy. Results of the FTIR and turbidity experiments indicate that aT decreases or diminishes the effect of cholesterol on the frequency and the bandwidth of the C-H stretching, CH 2 scissoring and ...
