Infrared spectroscopy is increasingly established as a way to carry out in vitro diagnostic testing, thanks to its ability to detect the molecular profiles of many biomarkers. What has been missing, ...

All fibers were analyzed directly without additional modification or sampling accessories. The O-PTIR spectra resemble transmission-like IR spectra in non-contact (far-field) mode. Through spatially ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...
