Micro extraction by packed sorbent (MEPS™)

Micro extraction by packed sorbent (MEPS™)

Supplier: Trajan Scientific and Medical

Micro Extraction by Packed Sorbent (MEPS™) is a new development in the field of sample preparation by SPE (solid phase extraction). The MEPS™ product consists of two parts, the MEPS™ syringe and the MEPS™ Barrel Insert and Needle assembly (BIN). The MEPS™ approach to sample preparation is suitable for reversed phases, normal phases, mixed mode and ion exchange chemistries. Because MEPS™ BINs can be used for sample volumes as small as 10 µl it makes them particularly well suited to on-line use with LC-MS analysis of volume limited samples.

Solid phase microextraction fibers

Supplier: VARIAN

Solid phase microextraction (SPME) is a technique for extracting analytes from solid, liquid or gaseous samples by adsorbing them onto the SPME fiber and then desorbing them into an inlet, either on a gas chromatograph (GC) or an HPLC system. SPME is amenable to automation using an autosampler or it can be performed manually as well.
