Do you need to know how much your sample and internal standard are diluted?
Simply select your peristaltic pump tubing and our Dilution Factor Calculator will show you.
Sample is diluted by 10.5%
ie Final conc. of sample is 0.895 times initial concentration
Internal standard is diluted by 89.5%
ie Final conc. of internal standard is 0.105 times initial concentration
or Internal standard is diluted by a factor of 9.5
This calculation should be used as a guide only. Variations between pump tubes and roller pressures mean that the accuracy of the calculation cannot be guaranteed.
