Are You Sure Your ICP-MS Interferences Are Under Control?
In this summary, we will discuss how triple-quadrupole ICP-MS resolves interferences and improves accuracy for difficult elements and challenging applications. We will illustrate this with examples from a variety of applications. We will also present the new Agilent 8900 ICP-QQQ, which provides increased sensitivity, even lower detection limits, and hardware developments that provide greater flexibility to address emerging applications.
Scientists Unveil Better Mixing Rule for Absorption Spectroscopy of Aerosols and Colloids
June 16th 2025Researchers have introduced a simple yet powerful new rule based on Rayleigh scattering theory that accurately links the absorption behavior of composite media, like aerosols or colloids, to the properties of their nanoparticle constituents.
Short Tutorial: Complex-Valued Chemometrics for Composition Analysis
June 16th 2025In this tutorial, Thomas G. Mayerhöfer and Jürgen Popp introduce complex-valued chemometrics as a more physically grounded alternative to traditional intensity-based spectroscopy measurement methods. By incorporating both the real and imaginary parts of the complex refractive index of a sample, this approach preserves phase information and improves linearity with sample analyte concentration. The result is more robust and interpretable multivariate models, especially in systems affected by nonlinear effects or strong solvent and analyte interactions.
