Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview01:02

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

4.2K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for...

Raman Spectroscopy Instrumentation: Overview

A conventional Raman spectrophotometer includes a laser source, a sample holding system, a wavelength selector, and a detector.
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...

UV–Vis Spectrometers

3.1K
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

Raman Spectroscopy: Overview01:20

Raman Spectroscopy: Overview

1.2K
The underlying principle of Raman spectroscopy is based on the interaction between light and matter, specifically molecules' inelastic scattering of photons. When a monochromatic beam of light, typically from a laser source, interacts with a sample, most scattered light has the same frequency as the incident light. This is known as Rayleigh scattering.
However, a small fraction of the scattered light exhibits a frequency shift due to the exchange of energy between the incident photons and...

Area of Science:

  • Analytical Chemistry
  • Spectroscopy
  • Materials Science

Background:

  • Raman spectroscopy is a powerful chemical identification technique but limited in non-laboratory settings due to low sensitivity and slow acquisition.
  • Ultraviolet (UV) Raman spectroscopy can overcome these limitations by reducing background fluorescence and enhancing Raman scattering.
  • The effectiveness of UV Raman is highly dependent on target materials, morphology, and operational constraints.

Purpose of the Study:

  • To evaluate the optimal UV wavelength for trace explosive residue detection in checkpoint screening.
  • To analyze the trade-offs between different UV wavelengths (244, 266, and 355 nm) for specific applications.
  • To assess the impact of material properties and operational factors on UV Raman performance.

Main Methods:

  • Semi-empirical analysis of UV penetration depth for explosives and explosive-related compounds (ERCs).
  • Consideration of realistic particle sizes for explosive and ERC residues.
  • Evaluation of fluorescence signals from common checkpoint materials.
  • Assessment of UV Raman performance at 244, 266, and 355 nm.

Main Results:

  • Lower UV wavelengths generally provide superior performance for explosive detection.
  • The realized benefits of UV Raman can be significantly reduced by specific explosive types and substrate materials.
  • Fluorescence reduction and Raman enhancement are material-dependent, impacting overall sensitivity.

Conclusions:

  • While UV Raman shows promise for explosive detection, wavelength optimization is crucial and application-specific.
  • Logistical constraints such as size, weight, power, and cost may limit the adoption of the most optimal UV wavelengths.
  • Further research is needed to balance performance gains with practical implementation challenges in real-world scenarios.
