ROMIL-SpA^™ Super Purity Acids & Reagents

Key Applications Overview

Super Purity Performance at a Reasonable Cost

Today's users of pure acids and reagents in trace inorganic analysis well understand the importance of minimal background impurities.

And with environmental issues at the forefront of current analytical requirements they acknowledge the need to seek ever decreasing levels of contaminants. For them, ROMIL-SpA^™ Super Purity Acids and Reagents provide a practical solution by combining very high purity with a reasonable price.

Available are the major mineral acids, nitric*, hydrochloric*, hydrofluoric*, sulphuric*, perchloric* as well as acetic acid*, ammonia solution*, hydrogen peroxide and water.

Whereas other reagent suppliers simply batch select or distil their acids by traditional boiling the ROMIL products asterisked above are purified by sub-boiling distillation.

But what is so special about this technique that it imparts a greater purity to the finished product than traditional methods? Just look at the diagram. The secret lies in the smooth surface and fine vapour that is maintained over the liquid surface at a temperature just below the boiling point. This avoids the violent agitation and large scale mass transfer of contaminants that is inevitable with conventional distillation.

Remaining metallic impurities after sub-boiling distillation are generally in the region of less than 0.1-1 ppb and are confirmed by rigorous testing of each batch. To maintain these low levels most of the ROMIL-SpA^™ products are packaged in pre-cleaned glass bottles which have been fluorinated to reduce leaching, the 2½LT size being plastic coated for enhanced safety in handling. The remainder are filled in pre-cleaned polyethylene bottles.

Whether the instrumental application is atomic spectroscopy (AAS, GFAAS, ICP-AES, ICP-MS), ion chromatography or voltammetry, ROMIL-SpA^™ products are the ideal tools for today's routine inorganic trace analysis.
