Liquid raw material composition for cement grinding aid production Determination method gas chromatography

1 Scope

This standard specifies the gas chromatographic method for quantitative determination of liquid raw material components for the production of cement grinding aids, including principles, test conditions, and tests. Agents and materials, instruments and equipment, test procedures, test data processing, precision. This standard applies to the production of cement grinding aid triethanolamine, triisopropanolamine (including isomers), diethylene glycol, diethanol monoisopropyl Alcoholamine (containing isomers), single or mixed liquid raw materials free of inorganic substances and having a mass fraction of less than 85%.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document.

3 Principle

Gas chromatography was used to separate the components of the sample under selected operating conditions and detected by a hydrogen flame ionization tester. in accordance with The standard curve was drawn and quantitatively tested using the external standard method.

4 test conditions

The laboratory temperature should be controlled within the range of 20 ° C ~ 25 ° C.

5 reagents and materials

5.1 Anhydrous ethanol. analytically pure. 5.2 High purity hydrogen. The volume fraction is not less than 99.999%. 5.3 High purity nitrogen. The volume fraction is not less than 99.999%. 5.4 Conventional compressed air. 5.5 External standard reagent. triethanolamine, triisopropanolamine, diethylene glycol, diethanol monoisopropanolamine reagent, should choose the chromatogram with analytical certificate Pure or analytically pure, wherein the mass fraction of triethanolamine, triisopropanolamine and diethylene glycol is not less than 99%, and the mass fraction of diethanol monoisopropanolamine Not less than 93%. Typical external standard reagents are triethanolamine (chromatographically pure) with a mass fraction of 99.595% and triisopropanolamine with a mass fraction of 99.7%. (Analytically pure, may contain isomers), diethylene glycol (chromatographic purity) with a mass fraction of 99.349%, diethanol monoisopropyl at a mass fraction of 93.9%
