5 lip 2006 · The developed method was found to be suitable for rout ine analysis of aspirin and pravastatin simultaneous in the presence of its stress degradation products.
14 lis 2019 · Analysis of aspirin with IR. This document analyzes aspirin and its structure, mechanism of action, and case study using vibrational analysis. It begins with an introduction to aspirin, noting that it is used to treat inflammation, pain, fever, and can decrease risks of heart attack and cancer.

Résumé. Nous avons développé une méthode de spectrométrie infrarouge transformée de Fourier (FT-IR) pour la mesure rapide et directe de l’acide acétylsalicylique (ASA) dans différents produits pharmaceutiques.
Infrared spectrometry (IR) provides a useful way for the identification of drugs. However, traditional techniques for obtaining IR spectra, such as alkali halide disks, mulls, and thin films, are not always adequate for quantitative analysis. FT-IR allows for the simultaneous analysis of several sample components and the
31 maj 1996 · The theoretical infrared data for the free aspirin anion are in good agreement with the experimental data for aspirin alkali-metal salts in dimethyl sulfoxide-d6.
The IR spectrophotometry aims to identify the active substance and compare these types of aspirin. Figure 3 shows the IR spectra for three different types of aspirin tablets (simple (A2), aspirin buffered (A5) and effervescent aspirin (A7)). Figure 3. FTIR spectra of simple aspirin (A2), bufferedand (A5) and effervescent (A7).
