Step-by-Step Procedure 1. Prepare the Smear Take a clean, grease-free glass slide. Place a small drop of sterile water on the slide if using a colony from solid media.Mix a small amount of bacterial colony into the drop and spread…

Diclofenac Sodium Assay Method Methanol Dissolution and Titration Method Principle Diclofenac Sodium is dissolved in methanol and titrated with 0.1 M sodium hydroxide (NaOH). The amount of Diclofenac Sodium present in the sample is calculated from the volume of NaOH…

Method 1: Non-Aqueous Titration Method Principle Diclofenac sodium is titrated in a non-aqueous medium using 0.1 M perchloric acid. This Diclofenac Sodium Assay (Titration) method 1 is suitable because diclofenac sodium behaves properly in non-aqueous solvent systems. Reagents Required Procedure…

Since both standard and sample final concentrations are same, assay is calculated by direct absorbance comparison. Formula % Assay=Sample ODStandard OD×100\% \text{ Assay} = \frac{\text{Sample OD}}{\text{Standard OD}} \times 100% Assay=Standard ODSample OD​×100 Substitution % Assay=0.4980.512×100\% \text{ Assay} = \frac{0.498}{0.512} \times 100 % Assay=0.5120.498​×100 =0.97265625×100= 0.97265625 \times 100 =0.97265625×100…
