Descripción

Descripción general

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol<TMSYMBOL></TMSYMBOL> solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol<TMSYMBOL></TMSYMBOL> solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified.

Aplicación

• Anthocyanin Separation: Acetonitrile is employed in high-performance liquid chromatography (HPLC) for the selective separation of anthocyanins. Studies have demonstrated the benefits of replacing acetonitrile with methanol in the mobile phase to control the selectivity and improve the resolution of anthocyanin separation, providing a more sustainable approach to chromatographic analysis (Deineka et al., Journal of Analytical Chemistry, 2021).


• Detection of α-Amino Acids: Acetonitrile is used in the development of chemiluminescence methods for detecting α-amino acids. A mixed solution of water, acetonitrile, and ethyl acetate has been shown to enhance the sensitivity and accuracy of amino acid detection, making it a valuable tool for biochemical and clinical analyses (Kan et al., American Journal of Analytical Chemistry, 2020).


• Electrochemical Detection of Biomarkers: Acetonitrile is utilized in the electrochemical detection of biomarkers such as 5-formyluracil. Labeling with (2-benzimidazolyl) acetonitrile enhances the selectivity and sensitivity of the detection, making it an important method for biomedical research and diagnostics (Tang et al., Analytical Chemistry, 2021).


• Ligand-Assisted Excitation of Europium Complexes: Acetonitrile is used in studying the ligand-assisted excitation of Eu(III) complexes. The interaction of europium complexes with xenon difluoride in acetonitrile solution provides insights into their photophysical properties, which are essential for developing luminescent materials for various applications, including lighting and display technologies (Masyagutova et al., Journal of Fluorine Chemistry, 2024).
