System suitability
Injections demonstrating the chromatographic system was performing acceptably when the sample was run. Required by every pharmacopoeia, documented on almost no research-peptide certificate.
Related terms
- Plate count (N)
- Column efficiency: N = 5.54 (t/w½)². Higher is sharper. The index requires N ≥ 20,000 for a main peak.
- 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.
