Fig. 5: Precise and accurate determination of lipid TIMSCCS values.
From: Trapped ion mobility spectrometry and PASEF enable in-depth lipidomics from minimal sample amounts
a Cross-instrument and cross-laboratory TIMSCCS measurement of a mixture of standard compounds (source data provided in Supplementary Data 8). Data labels indicate the coefficient of variation (CV) (n = 4 instruments). b CVs of TIMSCCS values for lipids commonly identified in replicate injections of a human plasma sample (n = 5 replicates, n = 1 instrument). c Pair-wise correlation of lipid TIMSCCS values from human plasma SRM 1950 measured on four different timsTOF Pro instruments. Relative deviation of experimental TIMSCCS values in this study (d) from literature reports23,24 and e machine learning predictions24.
