Fig. 4From: A simple and rapid extraction of lipids in plasma using spin column with superabsorbent polymer beads for mass spectrometryComparison of the limit of detection (LOD) of Matyash, SAP, and mSAP methods based on the calibration curve of XIC peak areas of the target lipid standards spiked in human plasma. The target lipids used for comparison were (a) PC (17:0/17:0) in the positive-ion mode and (b) PG (17:0/17:0) in the negative-ion mode. The error bars on the calibration curves represent the standard deviation of three replicates at each pointBack to article page
