ASTM E2037-15

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: E2037 − 07 E2037 − 15
Standard Test Method for
Bromine Chloride in Liquid Chlorine by High Performance
1
Liquid Chromatography (HPLC)
This standard is issued under the fixed designation E2037; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*Scope
1.1 This test method uses high performance liquid chromatography (HPLC) to determine bromine chloride levels in liquid
chlorine at the 10 to 1400 μg/g (ppm) range.
1.2 Review the current safety data sheet (SDS) for detailed information concerning toxicity, first aid procedures, and safety
precautions.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.No
other units of measurement are included in this standard.
1.3 Review the current material safety data sheet (MSDS) for detailed information concerning toxicity, first aid procedures, and
safety precautions.
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. Specific hazard statements are given in Section 8.

before the chlorine is allowed to evaporate. After the chlorine has evaporated the remaining eluent is analyzed directly on the
HPLC for bromine chloride concentration.

4. Significance and Use
4.1 This test method was developed for the determination of bromine chloride in liquid chlorine. Bromide is a common
contaminant in all salt sources that are used in the production of chlorine. This bromide content of the salt is converted into bromine
chloride in the liquid chlorine product. This test method is sensitive enough to measure the levels of bromine chloride observed
in normal production chlorine.
5. Interferences
5.1 This test method is selective for bromine chloride. At this time there are no known interference in the materials used in this
test method.
5.2 Contact with any metal surfaces should be avoi
