Standard Guide for Purity of Monomeric Plasticizers by Gas Chromatography

Importancia y uso:

5.1 Infrared techniques frequently cannot detect low-level materials. Gas chromatographic methods possess higher sensitivity and are used to extend limits of detection.

5.2 It is expected that this guide will be suitable for specifications, manufacturing control, and research and development. An area percent method of determining concentration of the components shall be used if the area percent of the plasticizer is 99.0 % or higher. However, if the area percent of the plasticizer is less than 99.0 % or if any question were to arise about the data, an internal standard shall be used.

5.3 Impurities potentially found in monomeric plasticizers include alcohols, dibasic acids, and monoesters.
