This week on Bench Boost Mike, Autumn, and Thomas dive deep into validation procedures for ICP-OES and ICP-MS methods. They discuss the importance of planning validation parameters early, understanding sample matrices & analyte levels, and achieving complete dissolution via appropriate digestions. They review the seven key validation parameters of accuracy, precision, detection limits, linearity, selectivity, robustness, and stability. They also outline best quality control practices including analyzing blanks, CCVs, duplicates, spikes, and implementing control charts.

This week on Bench Boost the team from Inorganic Ventures discusses avoiding precipitation during sample preparation. They review mining sample challenges including high concentrations of Ca, Fe, Al, & silicates, sulfate-rich matrices forming insoluble sulfates, and rare earth elements requiring a more acidic matrix. Thomas explains how hydrolysis leads to insoluble metal hydroxides and reviews prevention strategies. Liv outlines how to use Ksp and how temperature effects compound solubility. Lastly, Autumn covers alternative ligands, such as EDTA, for higher pH stability.

This week on Bench Boost on team spotlights mining analysis challenges on ICP-MS due to high total dissolved solids, aggressive digestions, and low-ppb targets requiring interference control. They review ICP-MS interference types, giving examples such as ArO on Fe, and ArCl on As. The team explains how collision cell (helium KED) is used to reduce polyatomics and how reaction cell gases are used for mass-shifting analytes or interferences. Finally, they discuss triple-quad ICP-MS principles for stronger mitigation and share method-planning tips: isotope tables, chloride/oxide checks, survey scans, dilution/argon dilution for TDS, matrix matching (including HCl), calibration choices, and internal standards.
