Qualitative matrix effect assessment of ten individually injected blank OF samples infused with a 10 ng/mL calibrator. All ten samples are overlaid on this total ion chromatogram along with a calibrator to more easily identify expected peak retention times for each compound. Identical to Fig. 1 the peaks correspond to the following compounds retention time (minutes) THCCOOH-gluc (1.20), THC-gluc (1.71), 11-OH-THC (2.22), THCCOOH (2.29), CBG (2.85), CBD (2.88), THC-V (2.88), CBN (3.35), THC (3.60), and THCA-A (3.91).
