Comparative Dataset of 3-Component Liquid Mixtures and 3-Component Solid Blends for Spectral Measurement and Multivariate Analysis

This dataset includes two related three-component experimental systems created for comparative analysis within a shared compositional framework. One system features ternary liquid mixtures, while the other consists of ternary solid blends. Both systems were developed within a three-component design space and measured to assess how similarly composed experimental designs behave under different physical conditions.<br>The purpose of the dataset is to support the study of spectral response and multivariate structure in systems that share the same nominal compositional logic but differ significantly in measurement context. In liquid mixtures, component distribution is generally more uniform within the sampled region. In solid blends, local heterogeneity, particle arrangement, and sampled volume can affect the observed signal. For that reason, the dataset may be useful for researchers interested in chemometrics, spectroscopy, multivariate analysis, measurement representativeness, and comparative interpretation of composition-based experimental designs.<br>The repository contains raw and processed measurement files, sample metadata, compositional details, and supporting documentation that explains the file structure, sample identifiers, and system definitions. The dataset is organized so that liquid and solid systems can be studied separately or compared within the same three-component design framework.
