Purgeable organic carbon

A separate and independent injection loop dispenses the sample for non-purgeable organic carbon measurements. 

Measuring purgeable organic carbon inorganic carbon and non-purgeable organic carbon... 

The DC 180 will calculate total organic carbon based on purgeable organic carbon and non-purgeable organic carbon results and include it in the report. Alternatively, total organic carbon may be determined as the difference of total carbon less inorganic carbon. 

The TC content of a sample can be subdivided into many fractions depending on the particular needs. The classification is often based on purely operational parameters, for example, the method used to release the carbon from the sample (examples include purgeable organic carbon—POC or acid-released organic carbon—AROC). Table 10.1 lists examples of the different fractions of TC that can be determined in liquid and solid samples. This particular classification is based on the determination of carbon content, but similar classifications could be prepared for other elements present in the pollutants. 

Purgeable organic carbon POC OC released by sparging. POC and VOC are often used... 

The measured responses included uv spectra (to measure the concentration of remaining phenol), the carbon concentration (measured as non-purgeable organic carbon, or NPOC), the peroxide (by titration), and the pH in a few cases HPLC was used to measure the concentrations of oxidation intermediates. 

Purgeable organic carbon POC Referred to as VOC (volatile organic carbon) the fraction of TOC removed from an aqueous solution by gas sparging under specified conditions...
