CLEAN CHEMISTRY TOOLS FOR
ATOMIC SPECTROSCOPY
The analyst must ‘think blank’. He must be aware of every step of the analytical procedure as to the effect on the blank. He must ask himself “If I do this, what is the effect on the blank?
– T. Murphy, The role of analytical blank in accurate trace analysis
Milestone Clean Chemistry Line offers innovative and complete portfolio of systems and accessories for analytical blank control and reduction in ultra-trace elemental analysis. There is a growing awareness that sample preparation should evolve to the same standards of newest analytical techniques, such as ICP-MS providing a number of factors that can make critical impact on analysis quality.
All these factors are related to reduction and control of analytical blank. To address this issue, Milestone developed a comprehensive line of products and accessories to reduce and control the analytical blank perfectly reflected in our ETHOS UP and ETHOS EASY microwave digestion systems.

Ultratrace inserts
The “Vessel-Inside-Vessel Technology” was developed by Milestone in the late 90s. Vessel-inside-vessel technology uses a smaller secondary vessel inside the primary microwave vessel.
Advantages include:
Less acid volume
Higher sample amount
Lower dilution factor
Better detection limit
Lower analytical blank

THINK BLANK
Clean Chemistry Tools for Atomic Spectroscopy
This book explains how a laboratory can reach full control of analytical blanks and sample preparation for obtaining accurate results. The application of instruments and strategies to control sample prep blank is often called a “Clean Chemistry” technique. This book discusses the factors impacting blank quality, in particular when microwave digestion is used, and reviews some Clean Chemistry products and technologies designed to help the analyst generate superior analytical data on their ICP-OES or ICP-MS instrumentation.
