LC-MS/MS Analysis of Drugs in Whole Blood
A Unique Solution for total Automation and Undisturbed Detection
Summary: 1) We developed a fully automated analysis platform for the routine determination of immunosuppressants in whole blood.
2) The native, anticoagulated whole blood sample is processed in-line by a heat-shock treatment. The resulting cell-disintegrated blood (CDB) then is subjected to multidimensional on-line SPE. 3) The use of three different SPE-cartridges and packings respectively allows a highly selective extraction of immunosuppressants and a highly efficient depletion of matrix components which otherwise would interfere with the ionisation process.This holds for hydrophilic compounds and especially for hydrophobic, late eluting phospholipids.
