Sample Preparation Details

Part No:8B-S100-TAK
Solid Phase Extraction (SPE) procedure:Note: The solvent volumes shown below are for a 30 mg bed mass. The solvent volumes will need to be adjusted for a smaller or larger bed mass.
Load:Load: 1 ml of analyte and internal standard (1.0 ug/ml) spiked Porcine serum acidified with 2% conc.H3PO4 .
(Dilute the serum spiked analyte 1: 1 with buffer or water as needed)
Dry:1min at 10'' of Hg
Final Prep and Analysis: Blow down to almost dryness under slow stream of N2. Reconstitute with mobile phase to 200 µL. Inject 50 uL on HPLC Inject: 50 µL on HPLC / UV-Vis Abs.-Fixed Wave. (UV) @ 210 nm (ambient)
