duoPUR Acid Distillation System

duoPUR and subPUR, sub-boiling distillation systems allow laboratories to make their own high purity acids at dramatically reduced costs. Offering an optimal purification method, this type of acid distillation uses contactless infrared lamps to vaporize the surface liquid at a temperature typically 20°C below the boiling point. The duoPUR allows the purification of the most common acids such as HNO3 and HCl.

Application Area:

Acid distillation for sample analysis in ICPMS

Extremely easy-to-use equipment. The production of ultra-pure acid is essential for our work in the determination of trace metals in pharma samples. In general, in our laboratory, production is carried out uninterruptedly throughout the week on an 8-hour/day basis, which demonstrates the robustness of the equipment. The acid produced complies with all the requirements of the monographs and analysis methodologies used, making it an extremely important part of the quality results reported. Absolutely recommended.

Application Area:

Analysis of heavy metals in products of animal origin

As a National Reference Lab of food safety, we were encommended to analyse certain heavy metals in products of animal origin as meat, milk, egg, fish and others. The techique we used for this purpose is liquid chromatography of high performace with inductively coupled plasma mass spectrometer (HPLC ICP-MS), method that requieres the less inputs of heavy metals from environment, reactants and glassware, that is why we were using nitric acid (HNO3) and chlorhydric acid (HCl) ultra trace quality, which is very expensive, but since we acquire the Milestone duoPUR with the aim of distill nitric acid and chlorhydric acid, both in its concentrated forms, we have saved a lot of money because we are now distilling HNO3 and HCl ACS quality, which are cheaper than ultratrace quality. I blindly recommend this equipment because is easy to use, to clean and is going to save you a lot of budget that you can use in consumables your lab could need.

duoPUR Acid Purification System allows laboratories to purify low-cost reagent grade acids

High-purity acids and reagents are critical to controlling the analytical blank, the “Achilles heel” of trace analysis, and to improving ICP-OES and ICP-MS detection limits. Reagent purity, cleanliness of the materials used in sample preparation, the laboratory environment, and the skill of the analyst are all factors that contribute to contamination. In this application note, Milestone presents the duoPUR and subCLEAN systems for cleaning reagent grade acids and avoiding the expense of purchasing the highest purity acids.

‘Total workflow’ sample preparation approach to optimize elemental analysis

In this video, Milestone advocates for a 'total workflow' approach to sample preparation in atomic spectroscopy for elemental analysis. The video emphasizes the significance of other often overlooked steps in the sample preparation process. It proposes methods to enhance various aspects of elemental analysis, including lab throughput, data quality, cost-effectiveness, and safety. Drawing on decades of experience, Milestone introduces tools designed to address routine tasks in sample preparation, covering parameters such as reagents handling, cleaning methods, supply of ultrapure acids, and digestion vessel management.


High-quality acids at reduced costs for trace metals analysis

Sub-boiling distillation has demonstrated to be the best technique and the most cost-effective approach in acid purification. Unlike conventional distillation, sub-boiling distillation prevents the formation of spray or droplets and yields very-high purity acids. This video demonstrates that the duoPUR by Milestone allows on-demand acid purification ensuring a continuous supply of fresh high-purity acids.
