Sample Preparation Goes Subzero: Ice Concentration Linked with Extractive Stirrer (ICECLES)

A new technique, ice concentration linked with extractive stirrer (ICECLES), provides highly efficient isolation of trace compounds from aqueous samples. ICECLES combines freeze concentration with stir-bar sorptive extraction into a seamless analytical extraction methodology. This month, we discuss how to perform this relatively simple technique, and discuss its advantages and limitations.
