IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

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 ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...
