MERCK 104718.2500 Isooctane for Spectroscopy Uvasol® CAS No.540-84-1
| Description |
|---|
| Catalogue Number | 104718 |
| Synonyms | 2,2,4-Trimethylpentane, Isobutyltrimethylmethane, iso-Octane |
| Description | Isooctane |
| 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. |
