With TNT810 and TNT811 how is Total Inorganic Carbon (TIC) determined?
TIC determination from TNT810 and TNT811.
When using TOC TNTplus Vial Test, LR (1.5 - 30.0 mg/L C; (Product # TNT810) and TOC TNTplus Vial Test, HR (30-300 mg/L C; (Product # TNT811), two test have to be done. If the shaker is not used the results are as Total Carbon (TC) which is both TIC and Total Organic Carbon (TOC). Two tests must be done to determine TIC: the test without the shaker is TC and the test with the shaker is TOC. Therefore, TIC it is the difference between TC and TOC (TC - TOC = TIC).
