Make your own ultrapure acids
Sub-boiling distillation has been demonstrated to be the best method and the most effective approach in acid purification.
Offering an optimal purification method for preparation of high purity reagents, 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.
In contrast to conventional distillation systems, where strong boiling action generating aerosolized particles results in contamination of the original liquid with the distillate, the duoPUR acid purification system using sub-boiling technology provides gentle surface evaporation preventing the formation of spray or droplets and yields to ultrapure acids.
The duoPUR offers an alternative to the purchase of expensive high purity acids for trace elemental analyses.

‘TOTAL WORKFLOW’ SAMPLE PREPARATION APPROACH
Look beyond sample digestion and consider the total sample preparation workflow for elemental analysis. Find ways to avoid workflow disruptions that have negative effects on your lab’s outcomes. Consider several parameters like reagents handling, cleaning approach, supply of ultrapure acids and the handling of digestion vessels.
Why 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.
In contrast to conventional distillation, where strong
boiling action generating aerosolized particles results in
contamination of the original liquid with the distillate,
a gentle surface evaporation during sub-boiling
distillation prevents the formation of spray or droplets and yields to a very high pure acid.
duoPUR Quartz sub-boiling system
The duoPUR consists of two quartz distillation units.
Each unit contains two infrared heating elements (1), a
water cooled condenser (2), a high-purity PFA collection
bottle (3), 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.
The distillation rate provides hundreds of mL per day, depending on the power setting and the temperature of
the cooling water.
