How To Calculate TOC wt% From Organic Rich Sedimentary Rocks. TOC is the Total Organic Carbon. After HCl Treatment with HCL, all the Carbonate will go out and only the remnant is the organic carbon in the residue.
Step1; In EA Elementry analyzer, calculate the C in mg. based on the peak of the combustion of the HCl treated the organic matter.
Step2; Weight the amount of HCl treated OM.
Step 3; weight the Organic matter before the HCl treatment.
Step 4; Weight the HCl treated OM.
Step 5; Calculate the raw organic matter based on the formula.
Based on the formula Calculate the TOC in Wt%.
