Dramatically lower your analytical blank in five simple steps

As metals chemists are well aware, when working at ppb and ppt levels, constituents of the blank contribute not only to the measured signal but also to the error in the blank. This uncertainty contributes to the overall error of the sample measurement for ICP and ICP-MS analysis.

To address this issue, Milestone has developed an integrated line of products to support clean chemistry sample preparation. Each product addresses a potential source of contamination in the sample preparation process:

• Sample-to-sample cross-contamination
  For cleaning your sample containers and apparatus, we recommend the TraceClean system.
• Reagent purity
  To make your own ultra-pure acids reliably and inexpensively, we recommend the duoPUR system.
• Sample preparation methods
  For digestion of your solids to homogeneous solutions, we recommend an Ethos digestion labstation.
• Sample preparation environment
  For clean evaporation and concentration of your samples, your microwave labstation can be outfitted with an MMR Evaporation Rotor.
• Vessel materials
  Your sample processing vessels should be composed only of the purest, most chemically inert materials available.

Any of these products can be used independently, to address an area of particular concern. They can also be used together, as a complete clean chemistry solution for your lab.

Every instrument purchase is accompanied by a free copy of our new, informative guide: Clean Chemistry: Techniques for the Modern Laboratory. This book can also be purchased separately; see the sidebar at right for details.

Milestone is pleased to offer our new video mini-CD on Clean Chemistry. This digital movie explores clean sample preparation techniques for today's trace metal analysis, covering everything from how to make your own ultra-pure acids to the best way to clean your labware and ICP accessories. Downloadable articles and technical information are supplied as part of our Clean Chemistry Review.
