ROBUSTNESS AND RUGGEDNESS
• Robustness and Ruggedness of the method was determined by subjecting the method to slight change in the method condition, individually, the:
• Change in Wavelength
LAMO at 306.80nm and 307.20 and CLO at 359.80nm and 360.20nm
• Change in instrument (UV-Vis Spectrophotometer model 1800 and 2450),
• Three replicates were made for the concentration (1, 3, 5 μg/ml of LAMO and 6, 18, 30 μg/ml of CLO) with different stock solution preparation.
