  Thanks for the video. Do you have a video just for potency assays and the main # between r1 and r2 guidline?

  when the drug has lower solubility, the drug will not get dissolved easily , it will be filtered out, so less or no response at initial timepoints, isn't it leads to false results and how drug having better solublity is a disadavantage in this case ---please clarify?

  Firstly, I would like to express my gratitude for your great efforts. I have a few questions, please: Why is ethanol not used instead of methanol? What is the benefit of a pore size of 120 angstroms or more or less in relation to the analyte I need to separate? How can I determine the polarity of my analyte before starting chromatographic separation to have an idea of the order of separation? What are the acceptance criteria for receiving a column with respect to the theoretical plate reference limit? Why does absorbance vary with different mobile phases or columns for the same components at the same wavelength? In the column regeneration process for normal phase chromatography, I use water in one step. Conversely, in reversed phase chromatography, heptane is sometimes used. Is this harmful to the silica? Why might different mobile phases alter the separation order of analytes, even though the principle of separation is based solely on the polarity of the analytes and the stationary phase?
