Sample Preparation Goes Subzero: Ice Concentration Linked with Extractive Stirrer (ICECLES)
January 1st 2020A 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.
