MATRIX AND ASSOCIATED SAMPLE OR MIXING CUP USED FOR REMOVING COMPONENTS OF A LIQUID SAMPLE

Abstract:

An insert mounted in a mixing cup and used by an automated chemical analyzer for removing a targeted component of a liquid sample includes a porous matrix formed of or carrying in an immobilized state functionalized particles having properties such that the targeted component of the liquid sample adheres to the functionalized particles. When the liquid sample is expelled from a disposable tip fitted on the end of a pipette forming part of the automated chemical analyzer into the mixing cup, the liquid sample is drawn into the matrix of the insert by capillary action, whereupon the targeted component of the liquid sample adheres to the immobilized functionalized particles of the matrix.
