Perform SPE Faster and With Smaller Volumes Using MEPS Syringes From SGE. Micro Extraction by Packed Sorbent (MEPS) is a new development in the field of sample preparation by SPE (solid phase extraction). MEPS performs the same function as SPE, namely the purification or speciation of samples, but with some significant differences: 

- MEPS works with much smaller samples (as small as 10µL) than full scale SPE

- MEPS can be fully automated – the sample processing, extraction and injection steps are performed on-line using the same syringe

- MEPS is applicable to GC and LC

- Significantly reduces the volume of solvents and sample needed 

The MEPS product consists of two parts, the MEPS Syringe and the MEPS Cartridge. The cartridge contains the SPE phase, and is built into the syringe needle. The cartridge is used with a 100µL or 250µL gas tight MEPS syringe that allows fluid handling at normal SPE pressures. When the cartridge is exhausted, or another phase is required, the cartridge is easily exchanged by simply unscrewing the locking nut and removing/replacing the cartridge.

Sample Size and Sensitivity:

Sample volumes as small as 10µL can be used or larger samples, 1mL or more, may be concentrated by taking multiple aliquots of 100µL or 250µL.

Automation:

The ability to prepare and inject samples on-line using a single device reduces sample processing time and the need for operator intervention. Typical cartridge life is conservatively about 40-100 samples but actual life is dependent on the sample matrix. The small quantity of phase in the MEPS cartridge can be easily and effectively washed between samples which removes the possibility of carry-over. This process simply is not practical on conventional SPE devices.

Flexible and Easy-to-use:

MEPS cartridges are available in a variety of common SPE phases. The dimensions of the sorbent bed ensure that the sorbent performance remains identical to conventional SPE devices used for extraction of similar samples. Sample preparation for complex biological samples is readily adapted to MEPS and reduces the volume of sample and reagents required for extraction when compared with conventional SPE and other "micro extraction procedures".

The MEPS approach to sample preparation is suitable for reversed phases, normal phases, mixed mode and ion exchange chemistries. Because MEPS cartridges can be used for sample volumes as small as 10µL it makes them particularly well suited to on-line use with LC-MS analysis of volume limited samples.

The current range of syringes may be used manually or when used in Thermo Scientific and CTC Analytics auto-injectors require no modification of the syringe mount. Cartridges are available in needle styles to suit LC and GC applications. Needles are packed in a sealed blister pack of 5 needles to ensure their integrity.
