Understanding Contaminant Analysis Techniques

I’ve been diving into contaminant analysis methods for environmental samples, and I’m curious about best practices for validating results. Specifically, how do you all ensure the accuracy and precision of your chemical analyses when dealing with complex matrices? I recently used HPLC for pesticide residue analysis, but I’m wondering what additional techniques could help improve data reliability in such cases.

It sounds like you’re on the right track with HPLC! I’ve found that incorporating techniques like solid-phase extraction can help clean up those complex matrices before analysis, making it easier to validate your results. Have you considered running any matrix-matched calibrations for better accuracy?
