Analysis Preparation Sample Size Notes
Total Alkalinity (TA) Filtered2 0.45 micron, 100 microliters saturated HgCl2 per 500 milliliters Minimum 100 milliliters per analysis Recommended sample size 250 milliliters (rinses and duplicates)
Total Carbon (TCO2) Filtered2 0.45 micron, 100 microliters saturated HgCl2 per 500 milliliters Minimum 20 milliliters per analysis Recommended sample size 90 milliliters (rinses and duplicates)
TA & TCO2 Filtered2 0.45 micron, 100 microliters saturated HgCl2 per 500 milliliters Minimum 120 milliliters per analysis Recommended sample size 340 milliters (rinses and duplicates)

Note 1. Duplicate analyses are performed on a minimum of 1 in every 10 samples: therefore, recommended sample size is double the minimum sample size.

Note 2. Sample filtering may not be required for open marine samples with few particulates.
