The volume of each impinger sample solution is measured and recorded. If an analysis other than hydrogen cyanide is to be done, then an aliquot of the sample is measured out for cyanide analysis into a 25 mL volumetric flask and diluted to volume with N NaOH. The entire sample may be used as the aliquot if no other analyses are required.
