Spectral analysis is used for the precise determination of the chemical composition of metallic materials. With Optical Emission Spectrometry (OES) and X-ray Fluorescence Analysis (XRF), even the smallest alloying elements can be reliably detected. Atomic spectroscopy instruments can be divided into three basic types, depending on whether the phenomenon measured is based on light absorption, emission or fluorescence. Although atomic fluorescence can provide lower detection limits for some metal ions, these instruments are less commonly.

Penetration Depends on Density: Heavier metals like gold allow for shallower X-ray penetration compared to lighter ones. This guide provides a comprehensive technical overview of the physics governing X-ray penetration, the factors that dictate information depth, and how to optimize XRF spectroscopic measurements for subsurface analysis. The penetration depth is not a fixed setting on the instrument; it is the result of a physical interaction between the X-ray beam and the specific material you are measuring. The depth of penetration can be calculated by the following equation: where I is the quantity of photons returning from the sample, I0 is the quantity of photons entering the sample, μ/ρ represents the mass attenuation coefficient of a given element for a particular matrix, and x represents the. ), Symposium on Strategic and Critical Materials Proceedings, November 13-14, 2015, Victoria, British Columbia.

Los dos detectores de muestras especializados de Duetta recogen fluorescencia en ángulo recto con la luz de excitación, y absorben directamente a través de la muestra. Las aplicaciones de infrarrojo cercano están creciendo rápidamente, y el Duetta está listo para enfrentar el desafío con la detección de fluorescencia desde 250 a 1,100 nm, mucho más allá del alcance de los PMT estándar. A la derecha se ve la emisión de vidrio de neodimio Detección NIR que compara Duetta (CCD) con equipos con PMT.
