| GERSTEL SPE
Performing Solid Phase Extraction (SPE)
manually can be time consuming and nerve-racking, especially
when recovery and reproducibility are lacking due to sample
variability. If SPE can be reliably automated, it becomes a much
more efficient and reproducible process. The GERSTEL Multi
Purpose Sampler (MPS) with Automated SPE Option for standard
cartridges provides several benefits compared with manual SPE:
- Improved recovery, precision and
reproducibility
- Maximized sample throughput by performing
SPE during GC or LC analysis of the preceding sample
- More than 50 percent time saving for
overall analysis, compared to manual process
Following the SPE clean-up steps, the MPS can
introduce the sample extract directly to an LC/MS or GC/MS
system for analysis. Alternatively, the MPS can be used as a
stand-alone sample preparation robot, preparing samples for
multiple LC/MS or GC/MS systems in your laboratory.
The GERSTEL SPE enables automated sample
preparation and analysis even for complex samples. Samples are
prepared in a simple and safe manner combining accurate results
with high throughput.
Easy transfer of your established
manual methods
The GERSTEL SPE is based on
standard 1 mL, 3 mL, and 6 mL SPE cartridges. Manual SPE methods
can be directly transferred to the MPS and automated.
High throughput
Analysis of up to 98 samples including sample preparation using
standard SPE cartridges.
Efficient
All sample preparation steps are
performed during analysis of the preceding sample for highest
productivity and system utilization.
Optimal timing
All samples receive identical
treatment for best reproducibility. Sample introduction to the
GC/MS or LC/MS system follows immediately after sample
preparation.
Highly controlled analysis
conditions
Defined volumes and constant flow rates provide highly
reproducible conditions and optimal results.
Internal Standard Addition
Automated liquid standard
addition provide improved Quality Assurance.
Contamination free
Transfer of eluent from the SPE
cartridge to the sample vial is performed using a disposable
syringe needle into a closed vial, eliminating the risk of carry
over.
Simple concept, highly rugged and
efficient
Conditioning, extraction and
elution of the cartridge is performed in one dedicated module
with minimal movement of the cartridge ensuring highest
efficiency and ruggedness.
Integrated method for SPE and GC/MS
or LC/MS analysis for simple
and error-free control of the complete system.
The MPS is a fully automated
sample preparation and sample introduction robot for GC/MS and
LC/MS. The complete system is easily and efficiently controlled
from the Agilent ChemStation software or from the GERSTEL
MAESTRO software. Sample preparation steps, including dilution,
mixing, adding standards or derivatization are picked by
mouse-click from a simple menu.
One method and one sequence table control the complete system
including sample prep and GC/MS or LC/MS analysis. |
