ROMIL Hi-Dry anhydrous solvents for water determination
ROMIL Hi-Dry – for applications that demand high purity, anhydrous solvents.

WATERBEACH, UK: ROMIL Ltd said that its Hi-Dry anhydrous solvents take the high purity concept of ROMIL-SpS Super Purity Solvents one step further. This exceptional range of solvents delivers extremely low water levels of 50 ppm (0.0050 percent) or less, with many products routinely manufactured to below 5 ppm (0.0005 percent), using coulometric Karl Fischer analysis to ensure specifications are met.

All ROMIL Hi-Dry solvents are supplied in packaging designed to maintain the anhydrous state achieved during purification. The amber glass bottles are oven dried to remove all traces of moisture before filling under inert dry nitrogen and sealing with a tamper-evident, screw-on Hi­Dry cap. The cap’s double seal design features a PTFE wad and self-sealing septum, helping to maintain chemical purity while enabling solvent to be withdrawn by syringe via the dispensing hole, which has been enlarged in response to customer feedback.

The standard ROMIL Hi-Dry range of solvents is complemented by pyridine-free ROMIL Hi-Dry KF reagents and calibrants, enabling Karl Fischer determination of water content without the accompanying hazard and unpleasant odour associated with traditional reagent formulations. Certified reference materials manufactured using Hi-Dry anhydrous solvents are also available for calibration of volumetric Karl Fischer reagents prior to use.
