Applying the concepts of green chemistry and sustainability to routine analysis is a challenging endeavor. Sample preparation plays a central role as it involves the use of concentrated acid for atomic spectroscopy analysis and organic solvents for chromatographic analysis. For years, Milestone has been offering approaches to making laboratories more sustainable.

Milestone's instruments are designed to minimize the use of harmful chemicals, utilizing lower volumes of reagents, and incorporating safer, greener alternatives for both the environment and chemists. At the same time, through their technologies, they have successfully reduced waste generation in laboratories, helping their customers achieve significant environmental benefits. The enhanced performance of Milestone's microwave digestion systems for elemental analysis enables the use of a reduced volume of acid at a lower concentration, leading to lower acid volume, less dilution, and reduced waste. Furthermore, Milestone's acid purification system enables the re-purification of contaminated acid, further minimizing waste.

The Direct Mercury Analyzer eliminates the need for sample preparation and the use of related chemistry, this instrument offers a greener pathway for mercury analysis, eliminating the risk of hazardous chemical exposure, enhancing both lab safety and environmental preservation.

Milestone's microwave extraction technology is designed to use only a fraction of the volume typically required by other techniques, thereby reducing both the initial volume and waste production. By optimizing reagent consumption, laboratories can efficiently analyze samples while being mindful of the environment.
