Microextraction in a packed syringe

MEPS has so far been applied mainly to the analysis of drugs in biological samples only one application for the extraction of PAHs in water has been published.26 One of the major advantages of the MEPS design is that the packed syringe can be used many times over, for example, more than 400 times for water samples. Moreover, the technique permits a fast handling time in the analysis of PAHs in water, the speed enhancement being 15 and 100 times compared to the literature procedures of solid-phase microextraction (SPME) and stir bar sorptive extraction (SBSE), respectively see Sections 4.2.3 and 4.2.4. [Pg.73]

Another recent possibility is to use online sample preparation techniques. Standard SPE cartridges can be used with commercial SPE automation coupled upfront with LC-MS/MS. Alternatively, microextraction by packed sorbent (MEPS) is a miniaturized SPE format intended to work with sample volumes as small as 10 pL. The MEPS sorbent bed is integrated into a syringe that allows for manipulations of low-volume samples, either manually or in... [Pg.24]
