Reference substances should be prepared to ensure they do not get rid of any in their potency. As a result it is necessary to validate the method will give trustworthy reference alternatives which have not been deactivated by weighing so very little that an mistake is developed; adsorption onto containers; decomposition by gentle; and decomposition from the solvent.
A mix of API spiked with impurities or degradation items out there as reference supplies can be used for a “cocktail” or a retention marker Answer. This marker Option is useful for additional method optimization and will serve as a procedure suitability exam (SST) Option in sample Evaluation (six,ten).
