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.




The duoPUR offers an alternative to the purchase of expensive high purity acids for trace elemental.

90% cost saving of ultra-pure acids by purifying low-cost reagent grade acidsHigh productivity, up to 400 mL per hour (duoPUR) and up to 60 mL per hour (subCLEAN)On-demand acid purificationRe-purification of contaminated acids
