Thermo Fisher Scientific (San Jose, California), has acquired Max Analytical Technologies (East Windsor, Connecticut). Max Analytical has developed Fourier-transform infrared (FT-IR) spectroscopy –based gas analysis solutions for process monitoring, source testing, and ambient air monitoring. Its systems are used extensively in semiconductor manufacturing, industrial process monitoring, and environmental health and safety applications. The Max Analytical portfolio complements Thermo Fisher’s line of FT-IR instruments, software, and services, and expands the breadth of Thermo’s vibrational spectroscopy products.
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.
