Laboratory use specifications and test methods GB/T 6682 Analysis
Preparation and Storage of samples 3
Eel samples taken after about 500g, eel sauce to remove surface samples taken about 500g, with minced meat grinder organization, into a clean container
As a sample, sealed and marked with tags. Sample preparation operation, should prevent sample contamination or the occurrence of the change of residue content. Sample Set
Save the following -18 ℃.
4 Method summary
Eel and eel in sulfa drugs extracted with methylene chloride. After the extract was concentrated, and the residue washed with acetonitrile and 5% aqueous acetic acid was dissolved by
Hexane liquid-liquid partition degreasing, eel samples subject to measure cation exchange high performance liquid chromatography solid phase extraction column purification with UV detection
Fixed, external standard.
5 Reagents and materials
Unless otherwise specified, all reagents were of analytical grade water as a water GB/T 6682 regulations.
5.1 dichloromethane. high performance liquid chromatography.
5.2 Methanol. HPLC grade.
5.3 acetonitrile. high performance liquid chromatography.
5.4 n-hexane.
5.5 glacial acetic acid.
5.6 hydrochloric acid.
5.7 ammonium acetate.
5.8 hexane saturated acetonitrile. n-hexane was mixed in sufficient acetonitrile, to saturation, visible layer of the container bottom layer of acetonitrile.
5.9 aqueous acetic acid. 1% (volume fraction), take glacial acetic acid (4.5) 10mL, water volume to 1L. Through 0.45μm membrane filters spare.
5.10 aqueous acetic acid. 5% (volume fraction), take glacial acetic acid 5.0mL, water volume to 100mL.
5.11 acetonitrile + water (1 + 1, volume ratio). Take 50mL of acetonitrile, was added 50mL of water, and mix.
5.12 aqueous hydrochloric acid. 0.1mol/L, take 9mL concentrated hydrochloric acid, adding an appropriate amount of water volume to 1L.
