1.1 This practice covers the determination of molecular weight (MW) averages and the molecular weight distribution (MWD) for soluble hydrocarbon and terpene resins by size-exclusion chromatography (SEC). This technique is not absolute; it requires calibration with standards of known molecular weight. This practice is applicable for samples containing molecular weight components that have elution volumes falling within the elution volume range defined by polystyrene standards.

Note 1-The SEC is also known as gel permeation chromatography (GPC).

1.2 The SEC systems employ low-volume liquid chromatography components and columns packed with relatively small (generally 3 to 20 m) microporous particles. High-performance liquid chromatography instrumentation and automated data handling systems for data acquisition and processing are also required.

1.3 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.
