Abstract

Disclosed is a device for a solid phase extraction comprising two or more of the sorbents to remove phospholipids and salts from a sample, to thereby eliminate matrix effects during mass spectrometry analysis. In particular, the sorbents includes at least one sorbent which is water-wettable and contains at least one hydrophobic component and at least one hydrophilic component and at least one of sorbent having a specific affinity for a matrix interference like phospholipids. Further disclosed is a method using the device of the present invention.
