Witryna12 wrz 2024 · Calculate the total contribution of the potential elemental impurity by summing the contributions across the components of the drug product. 6. Assess the variability of the elemental impurity level (s) in the components. 7. Enter the control threshold of each potential elemental impurity identified. WitrynaThere will be mostly two formulae which will be helpful for calculating RS by HPLC, 1) Calculating known impurity Level, 2) Calculating unknown impurity level. Calculating known impurity level : % of known impurity = ( Ri / Rs ) x 100 x RF % of unknown impurity = ( Ri / Rs ) x 100 May be right now, you may get a doubt
