Japanese Patent JP3033846
Kind Code:
B2
Abstract:
A method of radiochemical analysis having the steps of providing a solid phase extraction sheet material containing ion-specific sorptive or reactive particles in a porous matrix as carrier for the particles, and providing a fluid including an ion-containing radiochemical analyte, contacting the sheet material with the fluid for a time sufficient for the particles to selectively extract the analyte from the fluid, and analyzing the sheet material in a direct mode for quantitative or qualitative data relating to the radiochemical analyte. Solid phase extraction sheet materials and methods for their preparation are also disclosed.
