The fog collector came on at 11:00pm and was collected at 11:30 am. We got a full jar of ~270mL. The sample was split into 5 equal portions of 50mL each. The first aliquot was acidified immediately, then the next 3 will be acidified over the next 6 days at 2 day intervals. The last aliquot as been put in a cooler with no light exposure.
