Abstract
What is ISO 23973 about? ISO 23973 discusses liquid chromatography at critical conditions (LCCC). ISO 23973 specifies a valid method for the separation of chemically heterogeneous polyethylene oxide (PEO) mixtures and the determination of the number and content of the chemically heterogeneous species in the overall sample. The method presented under ISO 23973 serves as a technical guideline for learning the principle of “critical chromatography” on a validated system. Note: The method presented in ISO 23973 stated system parameters is not applicable for other polymer classes, due to the diversity of the interactions between the polymer/mobile phase/stationary phase and the number of separation systems that are therefore available. Who is ISO 23973 for? ISO 23973 on Liquid chromatography at critical conditions (LCCC) is relevant to:
