Environmental testing labs face constant pressure to deliver fast, accurate, and compliant results—often with limited time and resources. Optimizing sample preparation workflows can have a game-changing impact on productivity, safety, and data quality.
Milestone has condensed its industry expertise into a comprehensive free eBook: ‘Optimizing Sample Preparation Workflows for Heavy Metals and Organic Pollutants in Environmental Labs.’
Inside, you’ll find practical strategies and innovative solutions to:
- Streamline workflows for heavy metals and organic pollutants
- Reduce sample preparation time and minimize manual handling
- Enhance data reliability and regulatory compliance
- Improve lab safety by reducing exposure to hazardous substances
- Lower operational costs and achieve measurable ROI

What’s Inside:
The book introduces a step-by-step approach to optimizing workflows for heavy metals, beginning with direct mercury analysis using the DMA-80 evo, which requires no sample digestion. Compliant with EPA Method 7473, the system enables fast, safe, and reagent-free analysis, reducing costs by up to 90% compared to conventional CVAA methods.
For other heavy metals, a “total workflow” approach is recommended:
- Acid Purification (duoPUR): Generates ultra-pure acids on-demand using sub-boiling distillation, reducing dependency on commercial supplies and saving costs.
- Reagent Handling (easyFILL): Automates acid dispensing in a sealed environment, enhancing safety, precision, and efficiency.
- Vessel Handling (easyCAP): Automates capping of digestion vessels, minimizing operator fatigue and ensuring sealing consistency.
- Microwave Digestion (ETHOS UP / ultraWAVE 3): Provides rapid, complete, EPA-compliant digestion with high throughput and minimal contamination. The ultraWAVE 3 supports mixed matrices and uses disposable glass vials to eliminate cleaning.
- Filtration (SFS-24): Allows simultaneous filtration of 24 samples under vacuum, improving speed and reducing cross-contamination.
- Labware Cleaning (traceCLEAN): Uses acid steam in a closed chamber to clean vessels safely and efficiently, freeing digestion systems for core activities.
This section outlines optimized workflows for analyzing organic pollutants, typically extracted with solvents. Traditional methods like Soxhlet and PFE are laborious, slow, and hazardous.
- Reagent Handling (easyFILL): Automates acid dispensing in a sealed environment, enhancing safety, precision, and efficiency.
- Microwave Extraction (ETHOS X): Replaces older methods with fast, reproducible extraction using disposable glass vials, reducing solvent use and eliminating cleaning steps. Processes 24 samples in 40 minutes.
- Filtration (SFS-24): As with metals, enables simultaneous filtration, improving efficiency.
- Disposable inserts further eliminate cross-contamination risks and reduce labor.
