Advantages of automation
The
sensitive analysis requires concentration prior to the analysis. This
labor-intensive step of sample preparation can be fully automated. While
the analysis is running, the next sample is prepared. High
reproducibility is guaranteed by special cartridges and precise delivery
of the eluent with a high-pressure syringe pump. A variety of packing
materials for the cartridges allows high flexibility.
- Avoidance
of carry over - on the one hand by flexible flushing options that allow
cartridges to be reused without risk, and on the other hand by the
possibility of changing cartridges fully automatically
- Low sample volume due to more powerful detection systems and robust, routine large-volume injection
Technical structure of the online SPE system
The
online SPE system consists of a high-pressure syringe pump that
delivers sample and eluent, a cartridge exchange module, a CHRONECT
Robotic Autosampler and an OPTIC Large-Volume Injector. This online SPE
system can be connected to any GC/MS system.
