Extended Data Fig. 4: Noise level after sub-pixel spectral drift correction.

Blue line: the SC spectrum of 1% d34-hexadecane oil emulsion. Purple line: SC spectrum from a water-subtract-water negative control. We performed two parallel measurements on the pure water sample, treating one measurement as the solvent spectrum and the other as solution spectrum. After sub-pixel spectral drift correction, the noise level of the negative control is approaching the technical noise level and is way lower than our measured SC spectrum of oil emulsion. This comparison supports the experimental reliability.
