UC知道SPE elution solvent efficiency 翻译

Due to the wide ranging analyte polarity,the optimum elution
solvent system had to incorporate a series of solvents to elute
all the analytes effectively.After conditioning and equilibrating
the solid phase extraction cartridges,1 mL of a mixed stan-
dard solution containing all the seven analytes at 500 g/L level
were loaded onto their respective cartridges(identified as SPE-
1 to SPE-4),washed with 20%methanol solution,but eluted
using different elution solvent systems.Recoveries for all the
analytes(92.48%–100.14%),performed in triplicate(RSD%:
0.35%–2.88%),were superior in the eluate collected from SPE-
4 which had incorporated a series of elution solvents differing in
polarity(methanol,methanol:ethyl acetate(1:1,v/v),and ethyl
acetate)。
