Acid Purification

With more labs using ICP-MS to perform trace metals analysis, the use of high purity (10 ppt) grade acid (to meet ICP-MS reagent quality requirements) has increased dramatically. At the same time, lab consumables costs are coming under ever stricter control. As a result, more and more labs are producing their own 10 ppt grade acids by purifying much lower cost trace metal (1 ppb) grade acids. The easiest and most cost-effective way to do this is with the Savillex DST-1000 acid purification system.

Extremely easy to use, the DST-1000 is an integrated, compact system that fits in any fume hood and requires no cooling water. The DST-1000 operates unattended, producing 500 mL of high purity acid (HNO3, HCl or HF) or water in 
approximately  12 hours, and pays for itself in months or even weeks. The DST-1000 comprises of an all PFA chamber with integrated heater, and a 1 L Purillex PFA collection bottle with membrane vent to prevent airborne contamination. And unlike commercially available bottled high purity acid, which degrades each time the bottle is opened, the DST-1000 provides a continuous supply of freshly produced high purity acid, suitable for the most demanding applications such as semiconductor and geochemical. Labs around the world that have switched to the DST-1000 save $1000’s each year by eliminating high purity acid purchases – and many have multiple units. The DST-1000 has proven itself to be the most effective way to save consumables costs and improve ICP-MS data quality.

The DST-1000 Acid Purification System comes complete with controller, 1 L Purillex PFA collection bottle and bottle stand.

Savillex manufactures all its labware, bottles and sample introduction products from only the highest purity grades of PFA and FEP. The name TEFLON® is often used incorrectly when referring to products made from fluoropolymers. For example it is common to see the terms Teflon bottle, Teflon vial, Teflon cap etc. in scientific literature. In addition, many people assume that TEFLON® is PFA. In fact, TEFLON® is a registered trademark of E. I. du Pont de Nemours and Company, and refers to all fluoropolymer resins (PFA, FEP and PTFE) manufactured by DuPontTM.
