Molecular Spectroscopy Webinars
- Feb 25, 2012 — Dec 31, 2020
Join us for our one-hour-or-less webinars on a variety of molecular spectroscopy techniques and applications. Follow the links below for technique pages and webinar listings. The schedules are updated regularly.
Fourier transform infrared, or FT-IR, is an infrared spectroscopy where IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). The resulting spectrum represents the molecular absorption and transmission, creating a molecular fingerprint of the sample.
Typical applications: Method development for QA/QC, materials identification and troubleshooting, forensic investigation, deformulation, academic research, teaching
Market examples: Polymers, pharmaceuticals, fire science, forensic science, flavors, oils and general analytical
Near-infrared spectroscopy is a form of vibrational spectroscopy utilizing absorption or reflection measurements in the near-infrared region of the electromagnetic spectrum. NIR can be very useful in probing bulk materials with little or no sample preparation, and when combined with fiber optic probes NIR can provide continuous on-line process analysis.
Typical applications: process monitoring, quality control and raw material identification
Market examples: Pharmaceuticals, nutraceuticals, incoming materials, chemicals, food and beverage, biofuels
Raman spectroscopy is a scattering technique where the difference in energy from the incident light and the scattered light is equal to a vibrational transition for the molecule and is associated with a specific normal mode of the molecule.
Typical applications: Research, quality control, material identification, crystalline structure
Market examples: Drug analysis, geology/mineralogy, carbon/graphene, general analytical
UV-Visible spectroscopy measures the absorption or reflectance of light in the ultraviolet and/or visible region of the spectrum.
Typical applications: R&D, quality control, product appearance, quality assurance, teaching
Market examples: Education, food and beverage, pharmaceuticals and biotech, government, material manufacturing, environmental
