Answer / ravali
to identify a compound both or and sor r required.bcz SOR
depends on OR where as OR changes with concentration ,so
not stable.SOR=OR/C*Lwhere c=concentration,L=cell
length.for a unkown compound of known concentration SOR
does not changes with cocentration,so we can identify the
compound.

hii, i'm had a sample of 1L that gone through extraction & evaporation. i used 0.5ml of methanol for reconstitution before injecting the sample to HPLC. i made a calibration curve using a standard solution but now i'm confused about how to display the concentration i got from the sample. for ex. i got 0.2ug/ml how i'm gonna explane this is for the 1L ? please help .. i'll really appreciate it thanks
