Chemometric Calibration Drift & Recalibration (2D)

Process Analytical Technology depends on a spectroscopic calibration model translating a raw signal into a live quality reading — but that model is only as good as its last calibration. This 2D simulator runs a continuous stream of synthetic spectra through a simple univariate calibration, letting the instrument baseline drift away from the calibrated intercept exactly the way raw-material variability and sensor fouling do on a real line. Watch the amber prediction trace separate from the true green concentration on the strip-chart as bias accumulates below the scrolling spectral heatmap, track RMSEP and bias live, then pull a noisy reference lab sample and recalibrate to snap the model back into agreement. Drag the canvas to pan across the batch history and scroll or pinch to zoom in on either panel.
