Treatment and Preservation: DO NOT
RINSE VIAL. Completely fill vial with sample to exclude air bubbles. Preserve
all volatiles samples except samples for Schedules1306 and 4024 adjusting
sample with 1:1 HCl/H2O solution to a pH of 2. If free chlorine is present,
first add 25 mg of ascorbic acid to each vial before filling with sample,
then fill with sample and adjust the sample to a pH of 2. Protect sample from
sunlight, store sample at 4 deg C, ship immediat |
