Quantitative comparisons between a sample’s near-field spectrum (for example, Fig. 2) and its associated conventional FTIR absorption spectrum require that the geometry of the near-field ...

IR spectroscopy allows studying large sample areas with very high local resolution. A new detection system examines all points on the image simultaneously, ensuring average measuring time of only a ...

The infrared absorption spectrum of a sample can therefore be used as a molecular fingerprint by which to characterize its chemical composition. This has made infrared spectroscopy a widespread ...

Learn how Bruker's AFM-IR technology delivers unparalleled insights into polymer composition, performance, and structure at the nanoscale.

By comparing the paint spectrum to a library spectrum of alumina trihydrate (Figure 3D), the presence of alumina trihydrate, a filler that enhances the color in paints, is also confirmed in the sample ...

Water Vapor and CO 2 Interference: Water vapor and carbon dioxide in the atmosphere can absorb infrared light, leading to interference in the spectra.This necessitates careful sample preparation and ...

Conventional infrared spectroscopy focuses on the absorption step. By analysing the light transmitted through the material, ... (10-15 s), it delivers its energy to the sample within two oscillations ...
