3 Terms and Definitions
Terms and definitions defined in GA/T 122 apply to this document.
4 Principles
With blank samples and added samples as controls, the biological samples were extracted, purified and concentrated according to the requirements of parallel operations, and liquid chromatography was used
For detection by spectrum-mass spectrometry, the retention time, mass spectral characteristic ion pair and ion pair abundance ratio were used as the basis for qualitative judgment; the chromatographic peak area was used as the basis for qualitative judgment.
Quantitative analysis was carried out using the external standard-single point method.
5 Reagents, instruments and materials
5.1 Reagents
The experimental water should meet the first-class water specified in GB/T 6682.Unless otherwise stated, the reagents used in the analysis were of chromatographic grade,
The following reagents are included.
a) Methanol.
b) Acetonitrile.
c) Ammonium formate.
d) Formic acid.
e) Ethyl acetate.
f) 1% sodium hydroxide solution. weigh 1.0 g of sodium hydroxide, add a certain amount of water to dissolve and dilute to 100 mL.
