GA/T 122 Toxicological Analysis Terminology
3 Terms and Definitions
The terms and definitions defined in GA/T 122 apply to this document.
4 principles
The blank sample and the added sample were used as controls, and the biological samples were extracted, purified and concentrated according to the requirements of parallel operations, and liquid chromatography was used to
Spectrometry-mass spectrometry detection, based on retention time, mass spectrometry characteristic ion pair and ion pair abundance ratio as the basis for qualitative judgment; based on the peak area, the
Quantitative analysis was performed by external standard method.
5 Reagents and Materials
5.1 Reagents
The experimental water should meet the first-class water specified in GB/T 6682.Unless otherwise stated, all reagents used in the analysis were of analytical grade.
Reagents include.
a) Methanol (chromatographically pure);
b) Acetonitrile (chromatographically pure);
c) ethyl acetate;
d) 1% sodium hydroxide solution. weigh 1.0g of sodium hydroxide, add a certain amount of water to dissolve and dilute to 100mL;
e) Phosphate buffer (pH 6.0). Weigh 8.34 g of sodium dihydrogen phosphate and 0.87 g of disodium hydrogen phosphate respectively, add a certain amount of water
Dissolve and dilute to 1000mL;
