Popis

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

• Trichloroethylene, tetrachloroethylene and carbon tetrachloride in an urban atmosphere: mixing ratios and temporal patterns.: This study investigates the atmospheric concentrations of tetrachloroethylene and related compounds, highlighting their temporal patterns and implications for environmental monitoring and regulatory frameworks (de Blas et al., 2013).
