Excellent optical purity with a smooth spectral curve renders ROMIL‑SpS™ super purity solvents suitable for all UV applications. For work at short wavelengths we recommend that the solvent is nitrogen purged before use and that partially used solvents are stored under an inert atmosphere.
Test for Ultra-Violet Spectrometry:
The solvent is strongly purged with dry nitrogen for 30 seconds. UV Transmission values are then measured in a 10mm quartz cell using ROMIL Code H950 Water SpS as reference.
