Save hours in sample preparation, and go from extraction to injection in a single process with Thermo Scientific HyperSep MEPS (Micro Extraction by Packed Sorbent) Syringe Needle & Plunger for CTC Analytics technology.
MEPS Syringes and Components are suitable for reversed phases, normal phases, mixed mode or ion exchange chemistries and available in a variety of SPE phase chemistries. The HyperSep MEPS Barrel Insert and Needle Assembly (BIN) contains the stationary phase, and is built into the syringe needle.
HyperSep MEPS syringes and plunger assemblies operate exactly like conventional syringes and are easily replaceable.
MEPS performs the same functions as SPE—the removal of interfering matrix components and the selective isolation and concentration of analytes—except that it miniaturizes conventional SPE packed bed devices from milliliter bed volumes to microliter volumes, and incorporates them right into the syringe.
Mechanically robust, the technique offers significant advantages over conventional SPE extraction for method development and other GC and LC applications:
Significantly reduces the time to prepare and inject samples from hours to minutes—typically less than two minutes per sample
Eliminates all extra steps between sample preparation and sample injection; the technique is fully compatible with direct injection onto LC or GC
Reduces buffer and solvent volume from milliliters to microliters
Reduces the required sample volume to as little as 3.6µL, making the technique especially well-suited for on-line use with LC-MS analysis of volume-limited samples
Can easily be automated; the sample processing, extraction and injection steps are performed on-line using the same syringe (compatible with CTC and eVol platforms)
