Acid Purification

With more labs using ICP-MS to perform trace metals analysis, the need for high purity (10 ppt) grade acid to meet ICP-MS reagent quality requirements has increased dramatically. At the same time, lab costs are coming under ever stricter control. As a result, more and more labs are producing their own high purity 10 ppt grade acids by purifying lower cost trace metal (1 ppb) grade acids.  Savillex has created the easiest and most cost-effective way to meet this increasing demand with the Savillex DST-1000 and DST-4000 acid purification systems.  Both DST acid purification systems use the proven technique of sub-boiling acid distillation to produce high purity acid on demand - in any lab, at any time.  

Extremely easy to use, the DST systems are integrated, compact units that fit in any fume hood and do not require a cooling water supply.  The DST-1000 can produce 500 mL of high purity HNO3, HCl or HF (or water) in approximately 12 hours, while the higher capacity DST-4000 can produce twice the amount of the DST-1000 in the same time period.  Depending upon your lab’s acid needs, these units can pay for themselves in as little as a few months or even weeks.

Each DST acid purification unit consists of a self-contained PFA reservoir/condenser vessel (all wetted parts are PFA) with integrated heater and stand.  They are easy to fill and empty, and feature high purity Savillex Purillex™ PFA collection bottles for collection of the high purity acid distillate.  Unlike commercially available bottled high purity acid, which degrades each time the bottle is opened, the DST acid purification systems provide a continuous supply of freshly produced high purity acid, suitable for the most demanding applications such as semiconductor and geochemical analyses. Labs around the world using the DST-1000 and DST-4000 save $1000’s each year by eliminating high purity acid purchases.  Many labs have invested in multiple DST units to supply all of their acid needs.  The DST acid purification systems have proven to be the most effective way to save laboratory consumables costs and improve ICP-MS data quality.

A DST-1000 Upgrade Kit is available for older DST-1000 systems which allows users to upgrade their systems with the features of the current model.

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.
