A range of clean chemistry products from Milestone have been developed to reduce the number of analytical blanks and improve data quality. These products include the SubPUR Sub-Boiling Distillation System, the DUOPUR Sub-Boiling Distillation System, and the TraceCLEAN Automatic Acid Reflux System. The DUOPUR system can product approximately 1 liters of high purity acid from reagent grade acids in 6 hours at an affordable price. The TraceCLEAN system is a fully automated system with a typical cleaning cycle of an hour and the digestion vessels or sample introduction components are dry upon removal. These clean chemistry products provide cost and labor savings, and safer operation.
