MEPS (Micro Extraction by Packed Sorbent)

Trajan MEPS is Micro Extraction by Packed Sorbent, the miniaturization of conventional SPE packed bed devices from milliliter bed volumes to microliter volumes. The MEPS approach to sample preparation is suitable for reversed phases, normal phases, mixed mode or ion exchange chemistries. Micro Extraction by Packed Sorbent (MEPS) is a new development in the field of SPE. The MEPS technology consists of a modified removable needle syringe and a needle assembly that contains the SPE sorbent material. MEPS performs the same function as SPE, namely the purification or speciation of samples, and works on smaller sample volumes than conventional SPE. Subsequently, MEPS reduces the volume of solvent needed, from milliliters to microliters, and is much faster - literally minutes per sample preparation

The MEPS Barrel Insert and Needle (BIN) assembly contains the stationary phase, and is built into the syringe needle. Using MEPS requires both a suitable syringe and a MEPS BIN. With MEPS, the sample processing, extraction and injection steps are performed using the same syringe.
