Controlling Contamination in Your Laboratory

Advances in modern analytical instrumentation have made it possible to perform sub-ppb determinations on a routine basis. The analyte levels in the blank may be significant when compared to the sample. so the uncertainty of the blank measurement can obscure the accuracy of the result. Clean handling techniques are required for this type of analysis.

Milestone offers two systems which—together or independently—will help you prepare for clean microwave digestion, without contaminating your samples. The duoPUR system allows you to produce your own high-purity acids. The TraceClean system performs automated acid steam cleaning of your digestion vessels.

The duoPUR Sub-Boiling Distillation System

For acid decomposition, the purity of the reagents used is extremely important to the overall blank level. The duoPUR economically, efficiently, and safely produces ultra-pure acids from reagent-grade stock. Purifying low-cost reagent-grade acids saves up to 90% of the cost of purchasing ultrapure acids. The duoPUR can also re-purify reagents that have become contaminated. To learn more about the duoPUR system, click here.

The TraceClean System

Perfect for unattended cleaning of all Teflon, glass, and quartz ultra-trace accessories, including microwave digestion vessels and ICP/ICP-MS accessories Teflon racks and holders to minimize handling of freshly cleaned items No worker exposure to acid vapors Greatly reduced consumption of acids To learn more about the TraceClean system, click here.
