Your diagnosis
one choiceSignal-response pattern matrix
Every cell is computed from the parameters that draw the traces in Diagnose, so the matrix and the chromatograms cannot disagree. Multipliers are relative to the historical reference. S/N uses 2H/h. TIC is the background count at the analyte RT, which sets the ionisation loss of analyte and IS. Blank is the analyte response in the blank after the highest standard, as % of the LOQ response.
↑ above reference (×1.25 or more)
↓ below reference (×0.8 or less)

S/N: ≥10 · 3 to 10 · <3
TIC at RT: low ≤10⁶ · warning to 10⁸ · critical above 10⁸

Each card gives the signature, the mechanism, the test that separates it from look-alikes, and the corrective actions. The highlighted note follows the quantitation switch in the header.
