Further, the chromatogram of the standard concentration (100 μg/mL) of moxifloxacin showing no other peaks as shown in figure and confirms that the method is accurately identifying and measuring moxifloxacin without interference from excipients. This is a critical aspect of specificity, ensuring that the method is specific to moxifloxacin. Moreover, the chromatogram of the blank (0.1 N HCl) did not show any peaks. The blank is a control to ensure that the solvent used does not contribute any interfering signals. The absence of peaks in the blank supports the cleanliness and selectivity of the method. Therefore, the moxifloxacin test method demonstrates good specificity and is suitable for its intended purposes. The absence of peaks in the placebo,
