With isotope fingerprints sources of pollution, monitor water and air quality and track environmental change across space and time can be traced. Isotope Ratio Mass Spectrometry detects the “isotope fingerprint” of a sample, a unique chemical signature that changes from sample to sample across the environment.
Coated Wafer Mapping Using UV-Vis Spectral Reflection and Transmission Measurements
June 13th 2024This Agilent application note discusses the Cary 7000 UMS, a system for mapping coated wafers using UV-Vis spectral reflection and transmission measurements. It introduces a new autosampler for automated, high-resolution mapping of large samples and demonstrates its utility with a zinc tin oxide layer on a sapphire substrate.
