Resolution (R)
Separation between two peaks: R = 2(t₂ − t₁)/(w₁ + w₂). R = 1.5 is baseline resolution. The index requires R ≥ 1.20 to the nearest named impurity.
Related terms
- Rule AX-R12
- Peak asymmetry above 1.50 or resolution below 1.20 to the nearest impurity. Makes the reported purity a range rather than a number.
- Valley
- The minimum of the detector signal between two adjacent peaks. Valley height relative to the smaller peak determines whether the two can be reliably integrated separately.
