Title:
QUANTIFICATION METHOD OF NONIONIC SURFACTANT
Document Type and Number:
Japanese Patent JP2006226717
Kind Code:
A
Abstract:
To provide a quantification method of a nonionic surfactant capable of quantifying the composition ratio of a sample including two or more kinds of nonionic surfactants.
In this quantification method of the nonionic surfactant, a mass spectrum of the sample including two or more kinds of nonionic surfactants is measured by using mass spectrometry, and the composition ratio of the nonionic surfactants included in the sample is quantified from the intensity ratio of peaks of the nonionic surfactants included in the sample of the measured mass spectrum.
