What are the Advances in Sample Preparation Techniques?
Recent advances in sample preparation techniques have significantly improved the efficiency and accuracy of toxicological analyses: 1. Automation: Automated systems for sample preparation reduce human error and increase throughput. 2. Microextraction Techniques: Techniques such as Solid-Phase Microextraction (SPME) and Micro-SPE provide high sensitivity with minimal sample volumes. 3. Green Chemistry Approaches: Environmentally friendly methods that reduce the use of hazardous chemicals and solvents are being developed. 4. Nanotechnology: The use of nanoparticles in sample preparation can enhance the extraction and concentration of analytes.
