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.

To better understand modern sample preparation techniques-such as
ultrasound-assisted extraction, microwave-assisted extraction, and pressurized solvent extraction-we should look at the lessons these methods took from Soxhlet extraction.
