WebThe ATR-method is qualified for measuring aqueous solutions if the multiplereflection technique is used in such a way that strong water absorptions do not cover a large part of the information on the spectrum. The single-reflection technique is mainly suitable for solutions of 2-molar and higher concentrations.

Die ATR-Methode eignet sich für die IR-Spektroskopie von Kristallpulvern. Sie empfiehlt sich besonders dann, wenn die üblichen Methoden versagen, z.B. wenn Reaktionen mit dem Einbettungsmittel bei der KBr-Technik zu erwarten sind, oder wenn die Banden des Suspensionsmittels im Spektrum stören. 2.
Attenuated total reflection (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation. ATR uses a property of total internal reflection resulting in an evanescent wave. A beam of infrared light is passed through the ATR crystal in such a way that it refl… WebOct 12, 2024 · FTIR stands for ‘Fourier-transform infrared’ spectroscopy: a technique that can be used to procure an infrared spectrum of either the emission or absorption of a liquid, solid, or gas sample. An FTIR spectrometer synchronously collects the data of high-spectral-resolution over an extensive range.
WebMar 30, 2024 · In an ATR measurement, the beam of infrared light is directed through an infrared transparent medium which has higher refractive index to the sample which has lower refractive index, but in an external reflection measurement, the infrared beam is not directed through the infrared transparent medium. flea and tick remover for dogsWebatkl˛ja tiek atr e st s j˛m?
