NOTE 19—Since it is difficult to determine when there is 5 mL of
boiling liquid left in the flask, this time is determined by observing the
amount of liquid recovered in the receiving cylinder. The dynamic holdup
has been determined to be approximately 1.5 mL at this point. If there are
no front end losses, the amount of 5 mL in the flask can be assumed to
correspond with an amount of 93.5 mL in the receiving cylinder. This
amount has to be adjusted for the estimated amount of front end loss.
