Abstract

The invention discloses a laurinol polyoxyethylene ether fully two-dimensional separation analysis method including the following steps: an ultrahigh pressure hydrophilic interaction chromatography-ion mobility mass spectrometry coupled method is adopted, a laurinol polyoxyethylene ether fully two-dimensional separation analysis system is constructed, and effective separation and accurate determination of a complex target compound system are realized; the method includes optimization of ultrahigh hydrophilic interaction chromatography conditions and ion mobility mass spectrometry conditions. According to the laurinol polyoxyethylene ether fully two-dimensional separation analysis method, through the ultrahigh pressure hydrophilic interaction chromatography-ion mobility mass spectrometry coupling technique, the laurinol polyoxyethylene ether fully two-dimensional separation analysis method is developed, and rapid separation detection of laurinol polyoxyethylene ether is realized.

Description

technical field [0001] The invention relates to a comprehensive two-dimensional separation and analysis method for chemical substances, in particular to a comprehensive two-dimensional separation and analysis method for polyoxyethylene lauryl ether. Background technique [0002] Lauryl alcohol polyoxyethylene ether is an important fatty alcohol polyoxyethylene ether, and it is one of the fastest-growing and largest-used varieties of nonionic surfactants. The ether bond in the molecule is not easily destroyed by acid and alkali, so it has high stability, good water solubility, electrolyte resistance, easy biodegradation, and small foam. In addition to being widely used in the textile printing and dyeing industry, it is also widely used in compounding low-foaming liquid detergents. Lauryl alcohol polyoxyethylene ether has good compatibility with other surfactants. It is not sensitive to hard water and has good washing performance at low temperature, but its solubility will g...
