MSPE filters (Micro-Solid-Phase-Extraction)

18. 01. 2023

Micro-Solid-Phase-Extraction (MSPE) is a very simple sample preparation technique. MSPE uses a centrifugal filter with a membrane and a sorbent. MSPE tubes do not require the use of an SPE manifold and thus significantly simplify sample preparation for which a centrifuge is used. MSPE tubes are fitted with a membrane filter ensuring sample filtration after extraction. This avoids the use of syringe filters.

Sorbents for the MSPE technique are chosen to cover the widest possible field of applications.

• MSPE SpeExtra C18 is a hydrophobic type of octadecyl silica gel with a special endcapping with very wide application. It is suitable for a wide range of analytes, showing worse retention for polar compounds.
• MSPE SpeExtra C18-P is a polar modified monomeric octadecyl silica gel. It offers different types of interactions: dipole-dipole, π-π and hydrophobic. It is therefore suitable for aromatic and polar compounds.
• MSPE SpeExtra HLB polymer sorbent with high specific surface area and special endcaping. It has a hydrophilic and lipophilic modification ensuring universal use and a higher capacity than C18 silica gel.
