The weight fractions are plotted separately for all phases detected from a fast 1 min scans, b slow 10 min scans, and c adaptive scans. A short-lived intermediate phase, LaOOH, is detected only with adaptive measurements. Panels d–f illustrate XRD patterns obtained from the blue highlighted regions in panels a–c, which each should contain LaOOH. d A fast scan misses low-2θ peaks from this phase owing to a poor signal-to-noise ratio. e A slow scan misses high-2θ peaks as LaOOH transforms before the measurement is complete. f An adaptive scan successfully detects all peaks from this phase by performing a rapid scan over [10°, 60°], followed by resampling of [14°, 27°] to clarify the smaller peaks.
