Sample Preparation

Micro Extraction by Packed Sorbent (MEPS)

MEPS Syringe and Cartridge

MEPS performs the same function as SPE, namely the purification or speciation of samples, but with some significant differences:

  • Significantly decreases sample preparation time
  • MEPS can be fully automated – the sample processing, extraction and injection steps are performed on-line using the same syringe 
  • Significantly reduces the volume of solvents and sample needed
  • MEPS works with much smaller samples (as small as 10µL) than full scale SPE

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 dependant 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.
