3術(shù)語(yǔ)和定義

下列術(shù)語(yǔ)和定義適用于本文件。

3.1

加壓流體萃取儀pressurizedfluidextractor

利用加溫加壓萃取溶劑實(shí)現(xiàn)固體、半固體樣品中有機(jī)物組分快速萃取的一類(lèi)前處理設(shè)備（示意圖見(jiàn)

圖A.1）。

注1：加壓流體萃取儀也稱(chēng)為快速溶劑萃取儀或加速溶劑萃取儀。

注2：加壓流體萃取儀萃取過(guò)程中，萃取溫度和萃取壓力是影響萃取結(jié)果的核心參數(shù)。萃取壓力指萃取樣品時(shí)，萃

取池及其連通液路管的設(shè)置壓力。萃取溫度指萃取樣品時(shí)，加壓流體萃取儀內(nèi)部加熱爐的設(shè)置溫度。

3.2

加熱時(shí)間heatingtime

萃取池加載進(jìn)加熱爐后，開(kāi)始填充萃取溶劑，從萃取溶劑添加完成到靜態(tài)萃取開(kāi)始所保持的時(shí)間。

3.3

萃取池溫度平衡temperaturebalancebetweenextractioncellandheatingoven

加壓流體萃取儀萃取樣品時(shí)，含有樣品和萃取溶劑的萃取池內(nèi)部溫度與加熱爐溫度達(dá)到平衡的

過(guò)程。

3.4

靜態(tài)萃取時(shí)間staticextractiontime

加壓流體萃取儀萃取樣品時(shí)，從加熱時(shí)間結(jié)束即萃取溫度和壓力達(dá)到設(shè)定值后開(kāi)始萃取至一次萃取

循環(huán)結(jié)束所經(jīng)過(guò)的時(shí)間。
