Why use SPME?
-
A
variety of extraction phases for SPME fibers enables sampling of a wide
range of analytes.
- Enhanced
sensitivity compared to regular headspace sampling.
- Elimination
of solvent means reduced environmental impact.
- Applicable
to solid, liquid, and gaseous samples.
- Fully
automated using Sample Preparation Robots or Markes International's Centri® platform.
Automated SPME and SPME–trap
Markes
International’s fully automated Centri
system allows unattended SPME sampling, with or without secondary re-focusing.
Trap-based cryogen-free focusing results in enhanced sensitivity by allowing
multiple extraction cycles from a single sample to be ‘concentrated’ in one
GC–MS run, and results in improved peak shape and higher signal-to-noise ratios
for the most volatile, early-eluting species.
