Figure Lengend Snippet: Fig. 1 a External standard calibration curve with results of each sample (average of tripli- cate extractions). The error bars represent the standard deviation of the triplicate extractions and reflect the heterogeneity of the samples. All samples shown on the same calibration curve for simplicity. b LC-HRMS chromatograms of OTA in calibration standard solution 2 (Cal-2, 1.2 ng/g) and MYCO-1 extract (1.3 ng/g), revealing ion suppression

Figure Lengend Snippet: Fig. 2 a Experimental scheme for ID1MS (sample) and ID2MS (sample and calibration standard solution). OTA (A*) comes from the native working solution of diluted OTAN-1 and [13C6]-OTA (B) comes from the internal standard solution of diluted OTAL-1. b Unlabelled OTA and [13C6]-OTA exhibit similar elution and ionization profiles by LC-MS
