MERCK 108262.0025 Trifluoroacetic Acid for Spectroscopy Uvasol®
| Description |
|---|
| Catalogue Number | 108262 |
| Synonyms | TFA, TFA |
| Description | Trifluoroacetic acid |
| Overview | Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® 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® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. |
