Organic light-emitting diode display with organic small molecules Material purity determination by high performance liquid chromatography1 ScopeThis standard specifies the determination of organic small molecular materials in materials for organic light-emitting diode displays by high performance liquid chromatography (HPLC). (hereinafter referred to as OLED organic small molecule material) test method for purity. This standard applies to OLED organic small molecule materials that can be detected and stabilized by HPLC.2 Normative referencesThe following documents are indispensable for the application of this document.

OLED organic small points The daughter material is separated by a column and then detected by the detector based on its physical, chemical or other characteristics. A typical detector for HPLC is UV Visible light detector. The detector takes the response of each component and converts it into an electrical signal, which is then sent to the data processor.
