Step Scan / rapid scan: time-resolved FT-IR spectroscopy can achieve temporal resolution in ms, µs or ns range. It helps to follow very fast chemical reactions, to monitor repeatable physical processes or …

Aug 3, 2022 · Description: This article contains information on time-resolved step-scan and rapid-scan FT-IR Spectroscopy methods.

Nov 18, 2020 · A. FT-IR spectroscopy has 3 methods of time-resolved measurements: interval, rapid-scan, and step-scan measurements. The minimum time resolution for these methods is 1 second, 50 …

Measurement of a single scan temporally resolved transient process by rapid-scan FTIRTRS is only limited by the scan rate of the mirror, detector rise time, and digitization.

The rapid scan feature of the IRTracer-100 FTIR permits acquisition of 20 infrared spectra per second, enabling precise observation of the curing reaction process even when it is completed within a few …

The use of a phase-modulated step-scan interferometer in the PAS experiment offers the significant benefit that, in contrast to rapid-scan experiments, the sampling depth is constant across the IR …

For time-resolved measurements, both rapid-scan and step-scan measurement options are available for the FT/IR-6000 Series. Rapid-scan provides measurement up to a maximum of 20 Hz.

The FT/IR-6300 is equipped with gold optical surfaces for more efficient FT-Raman analysis and rapid scan capability as standard. Step scan, high resolution, and full vacuum options are available for all …

Feb 26, 2019 · Abstract For the first time, a standard rapid-scan Fourier-transform infrared (FT-IR) spectrometer was coupled with quantum cascade lasers (QCLs) tunable within the 1876–905 cm –1 …

The key collection parameters are: • The number of scans (background and sample) • The scan range • The spectral resolution. In general increasing the number of scans that are co-added improves the …
