The GERSTEL MultipurposeSampler (MPS) and its versatile sample preparation modules makes online sample preparation directly before injection possible. Its modular design means that many processes can be adapted and implemented.
The multi-functional autosampler with a broad range of applications.
GERSTEL SPEXOS expands your sample preparation portfolio with online SPE. Compared with sandard SPE, SPEXOS relies on much smaller cartridges with only 50 mg of sorbent, enabling a significant miniaturization of the entire process: Much smaller sample amounts are needed to reach required detection limits and much less solvent is needed for analyte elution reducing cost, simplifying logistics, and increasing method sensitivity.
Twister® Back Extraction as MPS Option
The combination of Twister technology (SBSE; Stir Bar Sorptive Extraction) with elution and subsequent chromatographic detection can be powerful and reproducible process for the determination of organic analytes from aqueous samples; e.g. PAH, psticides, herbicides or phenols.
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.
Extraction in Seconds
DPX is a fast and efficient SPE technique used for a wide rnge of applications such as drugs of abuse, therapeutic drug monitoring, comprehensive screening, pharmacology studies (NNK), as well as pesticides in fruit and vegetables. DPX is based on unique and patented SPE devices: Pipette tips that incorporate loosely contained sorbent material, which is mixed with the sample solution. Turbulent air bubble mixing creates a suspension of sorbent in the sample ensuring optimal contact and highly efficient extraction. The extraction is performed much faster than with traditional SPE techniques.
