title: Progress in field-assisted extraction and its application to solid sample analysis.
abstract: Sample preparation is the most time-consuming and laborious procedure during analysis. The rapid and effective extraction of solid and semi-solid samples is much more difficult than that of gas and liquid samples. In the present review, various extraction methods for solid and semi-solid samples such as supercritical fluid extraction, ultrasound-assisted extraction, microwave-assisted extraction, etc. are summarized based on the principles of field and field synergy effects. The expected trends of field-assisted extraction methods are discussed and proposed to encourage further development on the rapid and effective extraction for solid and semi-solid samples.
