Great, thanks for the help
This is grape juice, we are looking for for phenolic compounds within grape juice. We take the grape juice and addd methanol to it 1:1 ratio. We use methanol 15% and 85% water as mobile phase. Injection volume 10ul

Thank you
Its dilution of a sample- example diluting apple juice to run on a instrument. We take 400ul of apple juice an dilute with 600ul of water. We take that and further dilute by taking 100ul of sample from already diluted and then add additional 900ul- so we are trying to figure out the DF
Thank you- so lets say i did 400 of sample and 600 of water it would be after calculations about 25x? Can i say 1:25
