  • Publication number: 20250003930
    Abstract: First and second MRM transitions for a target substance, a first reference value concerning a measured intensity of the first MRM transition, and a second reference value concerning the measured-intensity ratio between the first and second MRM transitions are set. MRM measurements of an analyte sample using the first and second MRM transitions are performed to obtain a first intensity of the first MRM transition and a second intensity of the second MRM transition (Steps 11 and 12). The value of the first intensity is compared with the first reference value to determine whether the target substance is possibly contained (first determination; Step 14). For a target substance considered to be possibly contained in the analyte sample, the ratio between the first and second intensities is compared with the second reference value to determine whether the target substance is contained (second determination; Step 18).
