Örnek ilk olarak bir sıvı-sıvı faz çıkarımı ile, polar ve polar olmayan fraksiyonlar halinde ayrıldı ve kısmen aşağı analiz kolaylaştırmak için saflaştırılır. Ilk ekstraksiyon sulu (polar metabolitler) hem de organik (polar-olmayan metabolitleri) aşamaları metabolitlerin geniş bir anket için işlenir. Metabolitler kendi bölümü özelliklere bağlı olarak farklı sıvı kromatografisi yöntemleri ile ayrılırlar. Bu yöntemde, biz (UP) LC yöntemleri Mikrosirkülasyon ultra performanslı mevcut, ancak protokol daha yüksek akım ve düşük baskılara ölçeklenebilir. Kütle spektrometresi içine Giriş genel veya bileşik optimize edilmiş kaynak koşulları ya yoluyla olabilir.
