“…Sample extraction is a very important step that can lead to serious errors owing to the loss of a large amount of analyte (Andrade‐Eiroa et al, 2016 ). Therefore, many sample extraction methods have been developed and are constantly being modified, and new methods have been developed to achieve optimal analytical results (Lee, Cha, et al, 2021 ; Marín‐San Román et al, 2020 ; Serrano de la Hoz et al, 2016 ). Liquid–liquid extraction, solid‐phase extraction, simultaneous distillation extraction, and distillation under reduced pressure, which are well‐known conventional sample extraction techniques, have been reported to have several problems, such as low reproducibility, low selectivity, and difficult automatization (Marín‐San Román et al, 2020 ; Song et al, 2021 ).…”
