API Separation from Matrix Component
This Method for Analysis of Famotidine Tablets is easy to perform and produces a Symmetrical Peak Shape for the API. This compound has numerous amines which can be problematic in terms of Peak Shape with conventional Columns. Separation from a component from the tablet extract matrix is obtained as well, illustrating specificity of the Method.
Reproducibility is shown by the overlay of runs from two different Column lots.
Peaks:
1. Matrix Component
2. Famotidine
