SOLID PHASE EXTRACTION USING COMPOSITE SHEET FOR DIRECT MEASUREMENT OF RADIOACTIVITY |
摘要 |
<p>A method of radiochemical analysis comprises the steps of providing a solid phase extraction sheet material comprising ion-specific sorptive or reactive particles and a porous matrix as carrier for the particles, and providing a fluid including an ion-containing radiochemical analyte comprising the specific ion, 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.</p> |
