摘要
The influence of sample preparation on ion suppression is studied using the model compounds ropivaccine and 3OH-ropivocaine. Three sample preparation techniques are assessed: Solid Phase Extraction (SPE), Direct Dilution and Protein Precipitation. Although requiring more method development and being more time-consuming than the two alternative preparation techniques, SPE had a greater impact on reducing ion suppression.
