The present study is intended to develop the high-performance liquid chromatography (HPLC) method for the analysis of Canagliflozin using the analytical quality by design (AQbD) approach. It is a polymethacrylate gel. A flowing chromatogram, which is extensively used, is obtained by a procedure in which solvents are allowed to flow through the column until the separated drug appears in the effluent solution, known as the eluate. The drug may be determined in the eluate by titration or by a spectrophotometric or colorimetric method, or the solvent may be evaporated, leaving the drug in more or less pure form. In practice, separations frequently result from a combination of adsorption and partitioning effects. Fixed wavelength detectors operate at a single wavelength, typically 254 nm, emitted by a low-pressure mercury lamp. USP Chapter 621 for Chromatography - Tip301 - Waters This is conveniently determined from the length of the column and the retention time of a dilute methane sample, provided a flame-ionization detector is in use. 105 106 Plate height (H) (synonym: Height equivalent to one theoretical plate (HETP)) 107 Ratio of the column length (L), in micrometers, to the plate number (N): 108 H = 109 110 111 Plate number (N) (synonym: Number of theoretical plates) 2 USP: The United States Pharmacopeia, XX. Unless otherwise specified in the individual monograph, data from five replicate injections of the analyte are used to calculate the relative standard deviation, These tests are performed by collecting data from replicate injections of standard or other solutions as specified in the individual monograph.
