Hi Helmut and all members who contributed.

❝ I incorrectly assumed that you have a chiral method. Sorry.

No problem my friend!

❝ Validate the method with the racemate but state in the protocol that you will correct all concentrations once you have the l-enantiomer. Analyze the study samples with the racemate standards / QCs. This is a last resort - better than to wait for the enantiomer standard and risk that the samples degrade in the meantime. Avoid it in the future.

There is still time!!! :-D

Thank you so much! Now I understood that calibrators prepared and quality control samples concentration will not be accurate. Because weighing of standard is a racemate! So, concentration of unknown samples will be inaccurate. ;-)

S-Amlodipine, let's go! :cool:
