Total organic carbon (TOC) and total inorganic carbon (TIC) calibration system

A process for continuously maintaining the composition of an aqueous effluent stream from a solid phase, flow-through either one or both of Total Inorganic Carbon and Total Organic Carbon calibration standard modules at a predetermined standard condition, which comprises

• providing an on-line, gravity-independent, flow-through, solid-phase module for treating an aqueous influent stream;
• introducing said aqueous influent stream into said on-line, gravity-independent, flow-through, solid phase module;
• and
• treating said aqueous influent stream by combining therewith solid phase, flow-through preconditioning agents and either one or both of Total Inorganic Carbon and Total Organic Carbon calibration standard materials.

A system for calibrating a total carbon analyzer, comprising:

• (a) a sensor for sensing the level of carbon of a fluid stream and producing an output representative of the sensed level of said carbon;
• (b) means for supplying an influent fluid sample stream at a predetermined volumetric rate;
• (c) at least one solid phase standard module for imparting to said influent fluid sample stream a predetermined level of TIC or TOC;
• (d) means selectively operable to establish either one of first and second fluid sample stream flow paths, the first flow path providing said influent fluid sample stream through said solid phase standard means to said sensor, the second flow path by-passing the solid phase standard module;
• and
• (e) means for calibrating said output representative of the sensed level of said at least one of TIC and TOC with respect to said predetermined level of at least one of TIC and TOC in said influent fluid sample stream after the influent stream has been directed through said solid-phase standard module, including means for generating an output to said analyzer stream based on the predetermined level of either one or both of TIC and TOC.
