固相抽出（SPE）・QuEChERS
固相抽出（SPE）は、現時点において最も広く使用されている分析サンプル調製法の1つです。後に続くクロマトグラフィー分析のために迅速かつ選択的にサンプルを調製できるように設計されています。SPEでは液体サンプルから1種類以上の分析対象物を固体固定相に抽出、分配、および／または吸着し、分離します。
個別カートリッジ、96ウェルプレート、QuEChERSチューブ（分散SPE）、LiChrolut™ 抽出カラム・チューブなど、メルクが幅広く提供している製品をご覧ください。それぞれは、異なる固相ケミストリーで充填されており、真空マニホールドや専用アクセサリーを用いて処理できます。
