The MultiGas™ 2030 is an FTIR based analyzer capable of ppb to ppm With permanently stored calibration spectra, the need for costly gas cylinders is

technique to analyze the infrared spectrum of matter. Fourier-transform infrared spectroscopy ( FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.

Fourier transform infrared spectroscopy (FTIR) is a technique which is used to obtain infrared spectrum of absorption, emission, and photoconductivity of solid, liquid, and gas. It is used to detect different functional groups in PHB. FTIR spectrum is recorded between 4000 and 400 cm −1. FTIR Spectrum.

Figure 1 shows the Fourier transform infrared spectrum obtained from the polyurethane samples. The absorption band at 3323 cm−1 corresponds to NH stretching. The sharp peaks at 2859 cm−1 and 2938 cm−1 are associated with −CH2 stretching, while other modes of −CH2 vibrations are identified by the bands at 1464, 1418, 1364, and 1294 cm−1.

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.
