To maximise flexibility MEPS syringes are supplied without a needle and should be purchased separately.

Applicable to Manual and Autosampler use

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 easily semi-automated using the custom programming functions of the eVol® XR hand-held automated analytical syringe

MEPS can be fully automated – the sample processing, extraction and injection steps are performed on-line using the same syringe. For an examlple of this, please refer to "An automated method for the analysis of phenolic acids in plasma based on ion-pairing micro-extraction coupled on-line to gas chromatography/mass spectrometry with in-liner derivatisation", Peters, S., Kaal, E., Horsting, I., Janssen, H-G,. Journal of Chromatography A, 2012, 1226: 71-76.

MEPS is applicable to GC and LC

Significantly reduces the volume of solvents and sample needed
