Objective:

To explore sustainable practices in sample preparation and the role of automation, new materials, and education in advancing greener methodologies, emphasizing collaboration among academia, industry, and regulators.

Key Findings:

• Downscaling sample preparation reduces solvent use and energy consumption.
• Greenness assessment tools are available but need broader application in chromatography and mass spectrometry.
• Innovative techniques like ultrasound-assisted extraction can improve energy efficiency.
• Plastic waste from disposable lab items is a significant environmental concern.
• The next generation of scientists is more focused on sustainability in laboratory practices, as evidenced by recent studies.

Interpretation:

The shift towards greener sample preparation is underway, driven by new technologies and a growing awareness of sustainability among scientists. However, broader adoption requires simplification of methods, better training for laboratory personnel, and collaboration across sectors.

Limitations:

• Current greenness assessment methods are not uniformly applied across all analytical techniques.
• Many laboratories still rely on traditional practices that contribute to environmental impact, highlighting the need for innovative solutions.

Conclusion:

Sustainable sample preparation is critical for the future of analytical chemistry, and ongoing research, along with enhanced education and training, will lay the groundwork for more environmentally friendly practices in the coming years.
