With the right accessories, you can perform dynamic electrochemical studies; operate your system under operando conditions (operating live); examine catalysts under controlled environmental conditions, including temperature ...
Two of the characteristic absorptions of the mineral oil (1370 and 712 cm−1) occurred in regions that had no peaks in the dust spectra (standard spectra for wool and human skin). A calibration was produced by sequentially diluting the oil (Pea Soup) in petroleum ether (80–100 ...
1. Introduction Characterized by wavelengths longer than the mid-infrared region, the far-infrared region is also referred to as the terahertz region. In recent years, this region has been used to evaluate crystal polymorphs for pharmaceuticals and semiconductor device materials, as well as for arch...
. The MAX Gas Reference Editor is only available in the Advanced Software package and allows users to easily build calibration curves, attach traceability documentation, refine reference spectra by subtracting interferences or correcting baselines, and define primary & secondary quantification regions....

Sorghum flour had three major FTIR active regions from 1800 to 800 cm1. As expected, FTIR spectra revealed that starch was the primary compound in sorghum flour, followed by protein with only minor amounts of lipids and phenolic acids. Phenolic acids were characterized by a peak at 1709 cm1...
In order to develop PLS calibrations various spectral regions were investigated; however, the particular FT-IR region was chosen based on the lowest values of the root mean standard error of calibration (RMSEC) and highest values of the coefficient of determination (R2). An appropriate calibration...
Using the ConservatIR FTIR External Reflection accessory together with a Nicolet FTIR spectrometer, FTIR reflectance spectroscopy works well when applied to paint measurements in both the mid-IR and end-IR spectral regions. In our own tests, for example, we used mid-IR reflectance measurements to ...
The key concept is to find out which FTIR spectral regions are critical (i.e., the fingerprint regions) for the classification of each MP type through an Explainable Artificial Intelligence (XAI) method. Based on these identified spectral fingerprint regions, this work proposes a Fingerprint ...
