6. Interferences
6.1 Both nitrogen and sulfur interfere at concentrations
greater than approximately 0.1 %.
NOTE 1—To ensure reliable detectability, all sources of chloride contamination must be eliminated.
6.2 Bromides and iodides, if present, will be calculated as
chlorides. However, fluorides are not detected by this test
method.
6.3 Organic chloride values of samples containing inorganic
chlorides will be biased high due to partial recovery of
inorganic species during combustion. Interference from inorganic species can be reduced by water washing the sample
before analysis. This does not apply to water soluble samples.
