SCW Square-Wave Voltammetry Multi-label Dataset

This dataset was acquired using the Sensichips SCW water sensor and contains square-wave voltammetry measurements collected with multiple interdigitated electrodes (IDEs) (Platinum, Gold, Silver, Nickel, Palladium, Copper Oxide). It includes measurements of Citric Acid, Fructose, Sucrose, and Tap Water, as well as mixtures (“Artificial Juice”) combining the three substances at defined concentrations. Data are organized into three sets: Set 1 (Fixed concentration / sensor variability): same concentration per substance measured using multiple sensors; some sensors include multi-metal measurements, others Platinum-only; repeated runs are indicated. Set 2 (Variable concentration): multiple concentrations measured using a single sensor for each substance and for defined mixture recipes. Set 3 (Variable concentration + baseline): multiple concentrations measured using a single sensor and three metals (Gold, Copper, Nickel), with a tap-water baseline measured before each substance measurement and stored alongside the data. This dataset is suitable for ML experiments involving mixture/multi-label scenarios, robustness to sensor variability, and baseline-aware analysis.
