Standard Test Method for
Total and Organic Carbon in Water by High Temperature
Oxidation and Coulometric Detection1

This standard is issued under the fixed designation D 4129; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the determination of total and
organic carbon in water and wastewater, including brackish
waters and brines in the range from 2 to 20 000 mg/L. This test
the method has the advantage of a wide range of concentration
which may be determined without sample dilution and the
provision for boat or capillary introduction of samples containing sediments and particulate matter where syringe injection is
inappropriate.

1.2 This procedure is applicable only to that carbonaceous
matter in the sample that can be introduced into the reaction
zone. When syringe injection is used to introduce samples into
the combustion zone, the syringe needle opening size limits the
maximum size of particles that can be present in samples.
Sludge and sediment samples must be homogenized prior to
sampling with a micropipette or other appropriate sampler and
ladle introduction into the combustion zone is required.

1.3 The precision and biased information reported in this test
the method was obtained in collaborative testing that included
waters of the following types: distilled, deionized, potable,
natural, brine, municipal and industrial waste, and water
derived from oil shale retorting. Since the precision and bias
information reported may not apply to waters of all matrices, it
is the user’s responsibility to ensure the validity of this test
method on samples of other matrices.

1.4 This standard does not purport to address all of the
safety concerns, 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 specific
precautionary statements, see 9.1 and 10.2.1.
