Make your own HF, HNO3 and HCl acids

The chemical reagents used during the analysis are an important source of the analytical blank. Sub-boiling distillation systems has been demonstrated to be the the leading method of acid purification.
In contrast to acid purification through conventional distillation, where strong boiling action generating aerosolized particles results in contamination of the original liquid with the distillate, acid distillation system using sub-boiling technology prevents the formation of spray or droplets and yields to a very high pure acid.
The Milestone subCLEAN is a compact and easy-to-use sub-boiling system, where all parts in contact with acids are made of high-purity fluoropolymers. Offering an optimal purification method for preparation of high purity reagents, our subCLEAN system is therefore suitable for HF, as well as for HNO3 and hydrochloric acid purification.
  • Up to 90% cost saving of ultrapure acids
  • High productivity
  • ‘On-demand’ acid purification
  • Re-purification of contaminated acids

“In the preparation of high purity reagents, there is only one significant and practical choice for the method of purification: sub-boiling distillation"
US EPA SW-846, Chapter 3, Update IVB.

Why sub-boiling technology?

With subCLEAN system, the acid is automatically loaded into the distillation container, where it is gently heated below its boiling temperature. All process is microprocessor controlled by using a compact control terminal with easy-to-read, bright, full-color, touch-screen display.
The subCLEAN does not require cooling water or a chiller, as acid vapors rapidly condense into a collection bottle by forced air cooling.

Do you know how to reduce the sample prep blank?

Read our book! It explains how a laboratory can reach full control of analytical blanks and sample preparation for obtaining accurate results. The application of instruments and strategies to control sample prep blank is often called a “Clean Chemistry” technique. This book discusses the factors impacting blank quality, in particular when microwave digestion is used, and reviews some Clean Chemistry products and technologies designed to help the analyst generate superior analytical data on their ICP-OES or ICP-MS instrumentation.
