Dissolved Organic Carbon and Total Organic Carbon in water by Shimadzu

Detailed Description

Non-Purgeable Organic Carbon (NPOC) Analysis Using the Shimadzu 680°C Combustion Catalytic Oxidation/Non-Dispersive Infrared method.

The following standard operating procedure (SOP) is used by the U.S. Geological Survey’s Mercury Research Laboratory (MRL) to determine Dissolved Organic Carbon (DOC) or Total Organic Carbon (TOC) concentrations in water. This SOP describes the preparation of the sample and subsequent analysis. Sample analysis is conducted by the Shimadzu TOC-VCSH total organic carbon analyzer, using the NPOC analysis method. Quality assurance and control protocols are employed throughout sample analysis, including: laboratory practices to prevent sample contamination, method blanks, secondary standard checks, and analytical replication.
