Reporter view showing region 4 of the SPO fingerprint across a range of samples. 10% SPO + lab-pressed CPO and 10% SPO + Mill 2 Dispatch Tank (M2DT) are most similar to the pure SPO fingerprint. 1% SPO + M2DT CPO and 1% SPO + lab-pressed CPO share similarities with both pure SPO and diluted SPO headspace. This trend is repeated for all regions of the SPO fingerprint across all spiked lab-pressed CPO and DT CPO (data not shown)
