Absorption spectroscopy is one of the most widely used techniques employed for determining the concentrations of absorbing species (chromophores) in solutions. It is a nondestructive technique which biologists and biochemists and now systems biologists use to quantify the cellular components and characteristic parameters of functional molecules.

Atomic absorption spectroscopy
Journal of the American Oil Chemists' Society, 1968AbstractAtomic absorption spectrophotometry has been used for the rapid determination of various metallic and nonmetallic elements in crude and refined vegetable oils and in animal fats, many present in levels of parts per million. Various types of crude and refined vegetable oils were analyzed for Ca, Cu, Fe, Mg, Mn, P and Zn.

Photothermal Absorption Correlation Spectroscopy
ACS Nano, 2009Fluorescence correlation spectroscopy (FCS) is a popular technique, complementary to cell imaging for the investigation of dynamic processes in living cells. Based on fluorescence, this single molecule method suffers from artifacts originating from the poor fluorophore photophysics: photobleaching, blinking, and saturation.

Multiscattering-Enhanced Absorption Spectroscopy
Analytical Chemistry, 2015An original scheme for sensitive absorption measurements, particularly well-suited for low analyte concentrations, is presented. The technique is based on multiscattering-enhanced absorption spectroscopy (MEAS) and benefits from the advantages of conventional absorption spectroscopy: simplicity, rapidity, and low costs.

Concentration modulated absorption spectroscopy
Journal of Molecular Structure, 1985Concentration modulation is demonstrated to be a technique capable of markedly extending sensitivity limits in absorption spectroscopy. The gain generated relates in such a manner to sample transmittance that for the first reported time direct spectroscopic concentration measurements become possible.

Photothermal aerosol absorption spectroscopy
Applied Optics, 1985In situ aerosol absorption spectroscopy was performed using three photothermal detection schemes: phase fluctuation optical heterodyne spectroscopy, photothermal modulation of Mie scattering, and photophoresis. Particle specific absorption data of ammonium sulfate aerosols were obtained.

X-ray absorption spectroscopy (XAS) involves the excitation of core electrons to bound states localized on the photoabsorber and the eventual excitation of the photoelectron to the continuum. The resulting spectra are typically divided into two regions: (1) the edge region which provides electronic structure information and (2) the extended X-ray ...

Transient absorption spectroscopy
2022Die optischen Eigenschaften von organischen Farbstoffen und optisch aktiven anorganischen Molek len werden durch ihre chemische Struktur, ihrer chemischer Umgebung, und durch das Verhalten ihrer angeregten Zust nde bestimmt. Die klassischen Methoden zur Untersuchung dieser Eigenschaften sind die Absorptions- und Lumineszenzspektroskopie. Obwohl beide

Atomic Absorption Spectroscopy
Analytical Chemistry, 1960To monitor the internal state of the cuvette in an atomic absorption spectrometer, a video camera (16) is arranged to be capable of viewing the inside of a cuvette 10 within its sample furnace 2. Retractable mirrors M4 and M8, which are insertable simultaneously in the measurement path 7 to direct the radiation around the cuvette and along a reference ...

Photoacoustic X-Ray Absorption Spectroscopy
1988When materials are irradiated by X-rays, several effects occur, e. g. absorption, scattering, fluorescence, and electron release, as seen in Fig. 1. Heat generation should also be observed on absorption of electromagnetic waves even for the X-ray absorption process.
