I am using 2% w/v potassium dichromate reagent for the ethanol standards ranging from 2%-10% concentration but I am getting constsnt O.D. without any gradual increase. So, how can i resolve this issue to get a standard linear plot?

Plz find attachment.
use 2% alcohol stock solution for standard instead of 10%
I have attached the article for ethanol estimation using dichromate method.
I have a query regarding how to avoid smearing pattern of amplification product after performing reverse transcriptase PCR.
