(A) REIMS spectra comparison of the diathermy and the Harmonic data on porcine liver in the m/z range of 600–1000. High-intensity phospholipids were seen in the diathermy data compared to the Harmonic spectra where high-intensity diglycerides and triglycerides were seen. (B) Box plots showing some of the lipids that were of statistically significantly different relative abundance between the Harmonic and diathermy surgical tools, using a log scale of intensity. The box represents the interquartile range with the median shown. The whiskers represent the range of data points, excluding outliers, which were defined as five times the standard deviation from the median value. Additionally, raw data are represented using jitter points.
