This article explains about the method development process of pregabalin and the finalized optimized method and also gives a detailed note on parameters used for the validation of pregabalin. Validation parameters are the key things to be checked to access the method qualit...
For method development, three parameters play a role which are—with increasing significance—the compound retention (k), efficiency (N), and selectivity (a).A common way to adjust the selectivity is to change thecolumn chemistryand eluents. If thi...

The accuracy and reliability of the proposed method was ascertained by evaluating various validation parameters like linearity, precision, accuracy and specificity according to ICH guidelines. The proposed method provides an accurate and precise quality control tool for rout...
The USP assay method was modified to encompass the determination of two known impurities (neamine and kanamycin) and a degradation product (nebramine). The method development involved evaluation of several factors including derivatization parameters (time, temperature, and acid concentration), mobile ...
This article provides an overview of the current status, the benefits and the limitations of using UHPLC in method development. The long-term benefits of moving to UHPLC have been well documented elsewhere and we do not discuss them further [18], [19], [22], [26]. Table 2 summarizes ...
First, the goal of the method to be developed, which is called Analytical Target Profile (ATP), is defined and then critical method parameters (CMPs) that have impact on critical quality attributes (CQAs) are assigned. Various experimental designs have been performed during validation, development...
In the process of developing RPHPLC method three key parameters were studied which influence the selectivity such as chemistry of stationery phase, pH of the buffer, and organic modifiers. Phophate buffer with Octane sulphonicacid, pH was screened as pH3.0,4.0 and 5.0. HPLC columns were used ...
Parameters that were studied to evaluate the suitability of the system are given in Table 1. These parameters indicate good sensitivity, more ruggedness and robustness of the method. From the typical chromatogram of Lamivudine and Tenofovir disoproxil fumerate as shown in fig 2, it was found that...
The reliability of the developed method was validated using various parameters. Importantly, quantification of the aerial parts and roots of G. littoralis using the proposed analytical method showed that the majority of phenolic compounds were more abundant in the aerial parts than in the roots. ...
