1.1 This test method covers the determination of total organic carbon in water and wastewater, including brackish waters and brines.
Note 1-Test Methods D4129, D4779, and D4839 may also be used to measure carbon in water.
1.2 This procedure is applicable only to that carbonaceous matter in the sample that can be injected into the reaction zone. The syringe needle and injector opening size limit the maximum size of particles that can be injected into the reaction zone. Sludge and sediment samples should be suspended in water prior to sampling with a micropipet, where applicable.
1.3 In addition to laboratory analyses, these procedures may be applied to stream monitoring.
1.4 This test method is applicable to determining total organic carbon in water in the range from 2 to 200 mg/L.
1.5 It is the user's responsibility to ensure the validity of this test method on water of untested matrices.
1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Note A3.1.
