Data processing replicability for different data collection frequencies.
Samples shown in Fig. 1 were imaged using different frequency ranges. A total of 40 of the technical replicate deposits were subject to individual data processing for each frequency range. Mean representative spectra from the 40 technical replicates ± standard deviation are shown for (a) 199 (b) 14 and (c) 9 discrete frequencies.
