Descripción

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

• Preparation and application of stimuli-responsive PET TeMs: Utilizes RAFT graft block copolymerisation of styrene and acrylic acid for the separation of water-oil emulsions, demonstrating the adaptation of chloroform in enhancing polymer properties for environmental applications (Muslimova et al., 2024).


• Effect of Stool Sampling on a Routine Clinical Method: Describes the use of chloroform in gas chromatography-mass spectrometry for the quantification of short-chain fatty acids in stool samples, highlighting its importance in clinical diagnostics (Mahdi et al., 2024).


• Improved lipid analysis using a 2D-LC-MS system: Discusses a novel injection procedure involving chloroform for enhanced lipid profiling, showcasing its critical role in advanced biochemical analysis (Pánczél et al., 2024).


• Ecological Risk Assessment of Three Pesticide Additives in Soil: Addresses the application of chloroform in the remediation of contaminated soils, emphasizing its utility in environmental toxicology and soil science (Li et al., 2024).
