Ftir-spectrum.png ‎(428 × 286 pixels, file size: 3 KB, MIME type: image/png). File information. Structured data 1 Feb 2021 Attenuated total reflection (ATR) is a sampling technique used alongside traditional infrared spectroscopy, which ultimately qualifies samples to 13 Nov 2018 Recently, our GOgraphene powder was characterised by Fourier Transform Infra- Red Spectroscopy Attenuated Total Reflectance (FTIR-ATR).

FTIR spectroscopy is a great advance over the traditional dispersive infrared approach for a number of reasons including that the entire FTIR spectrum is collected in a fraction of a second and, by co-adding spectra, signal to-noise is improved. Die FTIR-Spektroskopie stellt einen grossen Fortschritt gegenüber dem herkömmlichen dispersiven Infrarotverfahren dar. Hierfür gibt es mehrere Gründe: Unter anderem wird das gesamte FTIR-Spektrum in einem Bruchteil einer Sekunde erfasst und das Signal-Rausch-Verhältnis wird durch das Hinzufügen von Spektren verbessert.

Fourier Transform Infrared Spectroscopy (FTIR) identifies chemical bonds in a molecule by producing an infrared absorption spectrum. The spectra produce a profile of the sample, a distinctive molecular fingerprint that can be used to screen and scan samples for many different components. output spectrum are calculated from the known frequency of the laser light. An FTIR spectrometer easily achieves frequency precision and accuracy of better than 0.01 wavenumbers. This means that spectra collected with an FTIR spectrometer can be quantitatively compared whether they were collected five minutes or five years apart.
