I have bulk fog water collected samples and I want to quantify Elemental and organic carbon concentration in it. We have ECOC analyser. How can I determine ec oc of the fog water sample. Though I know aerosol filter punch as it is put into ecoc analyser but how to find for fog water?
U can use OC/EC analyser of Sunset but u have to dilute100 times of the sample and suspended on Quartz filter. U can see the J. Collet paper.
The OC in fog water may be quantified using a high-temperature catalytic oxidation (HTCO) method on a total organic carbon analyzer. And the EC in fog water can be determined via the benzene polycarboxylic acids (BPCAs) method. Please refer to my recent work published in Global Biogeochemical Cycles (FangY_2018_GBC).
How did you quantify:
"smeared as even as possible" onto the filter for the DRI analysis
