MEPS™
MEPS'· - Micro Extraction by Packed Sorbent
MEPS'" (Patent Pending) performs the same funct ion as SPE, namely the purification or
speciation of samples, but with some significant advantages:
• MEPS'" can be a fully automated one step extraction and injection process- eliminate all
extra stepsbetween sample preparation and sample injection.
• MEPS'" workswith much smaller samples(assmall as3.6
~L)
than full scale SPE.
• Reduce buffer and solvent volume frommilliliters to microliters.
• MEPS'" isapplicable to GCand LC.
• Reduce sample handling times- from hours to minutes.
• Significantly increasesyour sample throughput - up to 20 x faster than SPME, 40 x faster
than SPEand 100 x faster than SBSE.
• Available in a variety of common SPEphases.
• Cost effective sample preparation compared to current techniques.
Sample Size
Sample volumes as small as 3.6
~L
can be used or larger samples, 1 mL or more, may be
concentrated by taking multiplealiquots of 100
~L
or 250
~L
Reusable
Typical Barrel-Insert-Needle (BIN) cartridge life is conservatively about 20-100 samples but
actual life is dependent on the sample matrix. The small quantity of phase in the MEPS'"
BINcan be easily and effective lywashed between sampleswhich removes the possibility of
carry-over. Thisprocesssimply isnot practical on conventional SPEdevices.
Flexible and Easy to Use
The MEPS'" BIN is easily installed into the syringe housing and then secured by the green
front locking nut. The dimensionsof the sorbent bed ensure that the sorbent performance
remains identical to conventional SPEdevicesused for extract ion of similar samples the BIN
cartridge contains
-3
mg of phase.
