Acid Purification System duoPur/subCLEAN
Milestone Inc | Sample Preparation - Inorganic
Think Pure
High-purity acids are critical to controlling the analytical blank, the "Achilles heel" of trace metals analysis. Once acid bottles are opened, you cannot always rely on commercially produced high-purity acids to remain free of the contaminants that affect your blanks. Furthermore, running out of high-purity acids can put your ICP-MS analyses on hold, which could have critical follow-on effects for your lab. Using the same sub-boiling distillation technology used to produce commercially-available high-purity acids, Milestone's duoPUR can safely produce fresh, high-purity acids on demand in your own laboratory at dramatically reduced costs, while giving you control of your acid supply.
Milestone duoPUR
Quartz sub-boiling system
The duoPUR consists of two quartz distillation units. Each unit contains two infrared heating elements, a water-cooled condenser, a high-purity PFA collection bottle, and a fully automatic acid loading/discharge system. The vaporized liquid is collected on the inclined water-cooled condenser and drips into the collection bottle. The distillation process is microprocessor controlled, allowing the user to set the distillation time and power level by using a compact control terminal with easy-to-read, bright, full-color, touch-screen display.
Distillation rates range from 50 to 400 mL per hour, depending on the power setting and cooling temperature.
How it Works
Sub-Boiling Technology:The chemical reagents used during the analysis are an important source of the analytical blank. Sub-boiling distillation has been demonstrated to be the best method of acid purification. It uses contactless infrared lamps to vaporize the surface liquid at a temperature typically 20° C below the boiling point. With conventional distillation, the boiling of acid generates aerosolized particles, resulting in contamination of the distillate. In contrast to this, gentle surface evaporation during sub-boiling distillation prevents the formation of spray or droplets, yielding high purity acids.
Advantages:The duoPUR offers an alternative to the purchase of expensive high purity acids for trace elemental analysis.
- Same technology used in the commercial production of acids for ultra-trace metals analysis
- 90% cost saving of ultra-pure acids by purifying low-cost reagent grade acids
- Purify the quantity you need, when you need it
- Uses high-purity quartz stills, which have no porosity or memory effect, and only get cleaner over time.
Because of this, laboratories purchase expensive high-purity acids for trace metal (element) analyses. With small samples sizes it is critical to keep blank levels low for good reproducibility. There is an alternative to the purchase of expensive high purity acids: Milestone has developed the DuoPUR and SubCLEAN, a sub-boiling distillation system which allows laboratories to make their own high purity acids at dramatically reduced costs.
