ASTM E1151-93 (2019) PDF

Full title and description

Standard Practice for Ion Chromatography Terms and Relationships. This practice defines terms, symbols, relationships, and common conventions used in ion chromatography — primarily techniques using ion-exchange separation and conductivity detection — and aligns terminology where appropriate with liquid chromatography practice E682.

Abstract

This practice provides a concise, standardized vocabulary and set of relationships for ion chromatography (IC) to promote clear communication among laboratories, instrument manufacturers, method developers, and standards writers. It covers definitions for system components, suppression approaches, injection systems, retention and peak descriptors, and recommended units (SI). The document is descriptive (practice) rather than a quantitative test method.

Scope

This practice deals primarily with identifying the terms and relationships for techniques that use ion-exchange chromatography to separate mixtures and typically use conductivity detection to detect the separated components. Where appropriate, terms and symbols from liquid chromatography Practice E682 are adopted to maintain consistency. The practice does not prescribe safety procedures or replace method-specific requirements.

Key topics and requirements

• Standardized terminology for ion chromatography system components (columns, suppressors, detectors, pumps, injection systems).
• Definitions and symbols for retention parameters, peak descriptors (height, base, width), and column characteristics.
• Descriptions of suppression techniques (chemical and electronic) and their effect on detection.
• Recommended units and the use of SI units for reported values.
• Alignment of IC terminology with liquid chromatography practice (cross-references to E682).
• Notes on applicability to other detectors and chromatographic variants where terms remain relevant.

Topics summarized from the practice text and document summary for the 2019 reapproval.

Typical use and users

Used by analytical chemists in environmental, pharmaceutical, petrochemical, and materials testing laboratories; instrument and consumables manufacturers; method authors and validators; educators and trainers; and standards committees to ensure consistent language, reporting and interpretation of ion chromatographic results.

FAQ

Q: What is this standard?

A: ASTM E1151-93 (reapproved 2019) is a Standard Practice that defines the terms and relationships used in ion chromatography to promote consistent vocabulary and reporting across laboratories and publications.

Q: What does it cover?

A: It covers definitions for system components, injection systems, retention parameters, peak descriptors, suppression methods (chemical and electronic), recommended units (SI), and alignment with liquid chromatography terminology. It is descriptive rather than a prescriptive test method.

Q: Who typically uses it?

A: Analytical laboratories (environmental, pharmaceutical, industrial), instrument manufacturers, method developers, educators, and standards writers use it to standardize terminology and reporting.

Q: Is it current or superseded?

A: The original standard was approved in 1993 and was reapproved in 2019 (commonly cited as E1151-93(2019)); the reapproved 2019 edition is the current edition (status shown as active/reapproved). Users should check ASTM for any later revisions after 2019.
