Differentiation of Leishmania species by FT-IR spectroscopy

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2015
Leishmaniasis is a parasitic infectious disease caused by protozoa that belong to the genus Leishmania. It is transmitted by the bite of an infected female Sand fly. The disease is endemic in 88 countries Desjeux (2001) [1] (16 developed countries and 72 developing countries) on four continents.

FT-IR spectroscopy: a powerful tool in pharmacology

Journal of Pharmaceutical and Biomedical Analysis, 2002
In the present work we report a Fourier Transform Infrared (FT-IR) analysis performed on rat encephalon samples in the CH-OH vibrational stretching region (2400-3800) cm(-1), in order to reveal the presence of a very diffuse commercial benzodiazepine: VALIUM.

Surface Analysis with FT-IR Emission Spectroscopy

Applied Spectroscopy, 1992
The technique of infrared emission spectroscopy (IRES) is reviewed and further examined in this study as a surface analysis tool. A system has been designed which allows simultaneous kinetic and in situ infrared emission analysis of catalyst surfaces.

Computers And Computing In FT-IR Spectroscopy

SPIE Proceedings, 1989
The state-of-the-art in inexpensive computing for FT-IR spectroscopy is examined. Problems concerning instrument communications, data transportability, networking using personal computers are explored. The use of personal computers in advanced chemometric applications is examined including applications of discriminant analysis for the classification of

FT-IR spectroscopy in catalysis

Acta Physica Hungarica, 1987
Supported metal catalysts are opaque to infrared rotation generally below 1200 cm−1 thereby preventing all the very important vibrations involving surface-adsorbate or “metal-ligand” motions from being observed by the conventional transmission technique. The possible methods which do not suffer from these limitations are summarized in this paper.

Comparison of FT-IR and Raman Spectroscopy

1980
Paralleling the evolution of Fourier Transform Infrared Spectroscopy during the 1960’s and 1970’s there have been rapid developments in the area of Raman spectroscopy. The laser serves only in a secondary role for FT-IR spectroscopy, but as a source for excitation it has greatly revolutionized conventional Raman spectroscopy and led to the advent of ...

MOISTURE MEASUREMENT BY FT-IR-SPECTROSCOPY

Drying Technology, 1994
ABSTRACT This contribution reports on the use of a FT-IR-spectrometer for measuring concentrations during the drying of thin films of Polyvinyl acetate (PVAc) and Methanol. Calibration was carried out by differential weighing. The spectra were taken in transmission mode while dried air was blown over the liquid films. The obtained accuracy was +/− (5% +

Reflection Spectroscopy With The FT-IR Microscope

SPIE Proceedings, 1989
The FT-IR microscope is a versatile sampling accessory used to record IR spectra in either transmittance or reflectance modes and capable of obtaining data from microscopic sampling areas. Because the FT-IR microscope simplifies the collection of reflectance data it has renewed interest in reflectance spectroscopy.

FT-IR Spectroscopy in an Industrial Laboratory

Applied Spectroscopy, 1984
FT-IR spectroscopy is used widely in many industrial laboratories. In combination with techniques such as gas chromatography, diffuse reflectance, and photoacoustic spectroscopy, it provides a means of tackling certain problems which would be impossible or at least very difficult and time-consuming with the use of dispersive Infrared instrumentation ...

Characterization and Identification of Micro-Organisms by FT-IR Spectroscopy and FT-IR Microscopy

1994
A large series of physical techniques has been tested for the characterization of microbial cells. These techniques include gas chromatographic (GC) and high-performance liquid chromatographic (HPLC) techniques, gel electrophoresis, pyrolysis mass spectroscopy, fluorescence and chemiluminescence techniques, flow cytometry, impedance measurements ...
