Ruggedness and Robustness
The ruggedness of the method was determined by carrying out the
experiment on different instruments like Shimadzu HPLC (LC 10
AT), Water Alliance 2695 by different operators using different
columns. Robustness of the method was determined by subjecting
the method to slight changes in the chromatographic conditions. It
was observed that there were no marked changes in the
chromatograms, which demonstrated that the RP- HPLC method
developed is rugged and robust.
