固相萃取 (SPE) 和 QuEChERS
固相萃取 (SPE) 是當今最流行的分析樣品製備技術之一。它專門用於為後續色譜分析製備快速且具有選擇性的樣品。在 SPE 中，液體樣品中的一種或多種分析物質透過萃取、分離和/或吸附到固體固定相上而被分離出來。
探索我們廣泛的產品系列，包括獨立試劑盒、96 孔板、QuEChERS 管 (分散式 SPE) 以及 LiChrolut® 萃取柱和管。每一種都包裝有不同的化學相，可使用真空歧管和專用配件進行處理。

- Brochure: HybridSPE® Phospholipid Removal Technology for Biological Matrices
Phospholipids are present as a major component of all cell membranes. They are therefore present in all biological sample matrices including serum, plasma and whole blood and can be a problem in LC-MS analysis of small molecules because they often co-elute and ionize along with the analytes of interest.
