General description

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.

Application


  • Quantitative determination of nitrous oxide in human blood by HS-GC-MS: forensic application of two fatal poisoning cases.: This study leverages n-Pentane in headspace gas chromatography-mass spectrometry (HS-GC-MS) for the forensic analysis of nitrous oxide in human blood. Highlighting its importance in forensic science, the research demonstrates n-Pentane′s utility in providing accurate and reliable measurements essential for legal and medical evaluations (Li Z et al., 2024).

  • A photochromic trinuclear dysprosium(iii) single-molecule magnet with two distinct relaxation processes.: This article describes the use of n-Pentane in the synthesis of a dysprosium-based single-molecule magnet, showcasing its role in developing materials with unique magnetic properties for potential applications in quantum computing and data storage (Rogacz K et al., 2024).

  • Reduction of Thorium Tris(amido)arene Complexes: Reversible Double and Single C-C Couplings.: This research employs n-Pentane in the study of thorium complexes, providing insights into reversible carbon-carbon coupling reactions. The findings contribute to the understanding of actinide chemistry and its application in recycling and waste reduction strategies (Deng C et al., 2024).

  • Tuning Reactivities of tert-Butyllithium by the Addition of Stoichiometric Amounts of Tetrahydrofuran.: The study utilizes n-Pentane to adjust the reactivity of tert-butyllithium, illustrating its significant role in enhancing the control over chemical reactions. This advancement is pivotal for the synthesis of complex molecules in pharmaceuticals and materials science (Kleinheider J et al., 2024).

  • Steps to achieve carvone-rich spearmint (Mentha spicata L.) essential oil: a case study on the use of different distillation methods.: In this research, n-Pentane is examined for its efficacy in extracting high-quality essential oils from spearmint, demonstrating its versatility in botanical extractions and its impact on the quality and characteristics of the essential oils obtained (Moradi-Sadr J et al., 2023).
