ایزو اکتان 104718 مرک Isooctane 104718 merck Isooctane for spectroscopy Uvasol(r). 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(r) 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(r) solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.
