Determination of Dimethyldiphenylurea in Dibase-Propellant by Gas Chromatography
气相色谱法测定仓储双基发射药二号中定剂含量

By using gas chromatography external standard method,dimethyldiphenylurea in the storage propellant was separated and determined. Being compared with the conventional bromination method, this one is more rapid, precise and reproducible. Moreover, it can provide reliable data for evaluationg the quality grade of the propellant.
