The Role of Atomic Spectrometers

The Role of Atomic Spectrometers

Atomic spectroscopy uses the electromagnetic radiation or mass spectrum of a sample to determine elemental composition. The wavelength of energy absorbed or emitted by atoms is characteristic to each element and can be used for element identification and quantification. Atomic spectroscopy is a technique that studies the interaction of light with atoms to reveal information about their electronic structure. It relies on the principle that when electrons in an atom change energy levels, they emit or absorb light at specific wavelengths unique to that element. Samples must be in liquid form before being placed in the analyzer. To do this, a chemist will use certain acids (nitric or hydrochloric) to extract the metallic component of a sample. It can be divided by atomization source or by the type of.

The Role of Fluorescent Fiber Sensors

The Role of Fluorescent Fiber Sensors

Fluorescent fiber sensors that fluoresce along the length of the fiber offer an advantage for detecting partial discharge (which generates UV and visible light), since light absorbed from any angle, along the entire length of the fiber, may be detected. Fluorescent materials integrated on the tips of optical fibers, for example, provide a means to perform fluorescence thermometry while monitoring the intensity or the spectral variations of the fluorescence signal. Similarly, certain molecules can be tracked by monitoring their characteristic. Fluorescence can be very simply defined as the emission of light when a material is exposed to electromagnetic radiation. This emission may continue for a period of time after the initial excitation. The length of time that a material will emit is a product of a number of interactions that occur at. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability.
