GB/T 6682 Specifications and test methods for water used in analytical laboratories
3 Terms and definitions
There are no terms or definitions that require definition in this document.
4 Principle
The glycyrrhizic acid in the sample was extracted with 50% methanol solution, purified by solid phase extraction column if necessary, separated by high performance liquid chromatography, and detected by ultraviolet detector.
Detection, qualitative analysis by retention time and quantitative analysis by external standard method.
5 Reagents or materials
Unless otherwise specified, only chromatographic grade reagents were used.
5.1 Reagents
5.1.1 Methanol (CH3OH).
5.1.2 Acetic acid (CH3COOH).
5.1.3 Ammonium acetate (C2H7O2N).
5.1.4 Water. Grade 1 water as specified in GB/T 6682.
5.2 Reagent preparation
5.2.1 50% methanol solution. Take 500 mL of methanol (5.1.1), dilute to 1000 mL with water and mix well.
5.2.2 Ammonium acetate-0.5% acetic acid solution (0.1 mol/L). Take 7.71 g of ammonium acetate (5.1.3) and 5 mL of acetic acid (5.1.2), dissolve in water and
Make up to 1000 mL and mix well.
