SORPTION OF WATER FROM A SAMPLE USING A POLYMERIC DRYING AGENT

摘要

A method of extracting an analyte from a sample is described where the sample includes water. The sample and polymeric drying agent are added to a container. The polymeric drying agent includes a cationic monomer, an anionic monomer, and a crosslinker. The polymeric drying agent is configured to sorb water from the sample.

1. A method of drying a sample, where the sample includes water, the method comprising:
adding the sample and a polymeric drying agent to a container, the polymeric drying agent comprising a cationic monomer, an anionic monomer, and a crosslinker, in which the sample includes water and an analyte, the cationic monomer comprises [3-methylacryloylamino)propyl]trimethylammonium chloride, the anionic monomer comprises 2-acrylamido-2-methyl-1-propanesulfonic acid, and the crosslinker comprises N,N′-methylenebis(acrylamide); and sorbing the water from the sample to the polymeric drying agent.
