Example Embodiment
[0033] Example 1
[0034] This embodiment provides a high performance liquid phase detection method for cement grinding aid diethanol monoisopropanolamine, which includes the following steps:
[0035] (1) Preparation of reference substance solution and test substance solution: accurately weigh out an appropriate amount of diethanol monoisopropanolamine reference substance, dissolve it with mobile phase and dilute to a constant volume to obtain a 10.0 mg / mL stock solution, and dilute it in sequence with mobile phase. 10.0, 20.0, 40.0, 60.0, 80.0μg / mL reference solution; accurately weigh 100.0mg of the test sample of diethanol monoisopropanolamine, place it in a 10mL volumetric flask, use the mobile phase (methanol and 0.1% acetic acid) The volume ratio of the aqueous solution is 80:20) Dissolve and fix the volume to obtain the test solution. If the solution is turbid, filter it with a 0.22μm filter to obtain the test solution; and use the mobile phase as the blank solution;
