The Agitator/Stirrer for the GERSTEL MultiPurpose Sampler (MPS) can either operate in agitation or stirring mode using conventional magnetic stir bars. Stirring helps efficiently mixing heterogeneous or viscous samples, accelerates equilibration for headspace sampling and extends the lifetime of SPME fibers.
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 Sample ID (SID) 1D/2D Barcode reader for the GERTEL MultiPurpose Sampler (MPS) uses a dual camera setup and image analysis for positive identification of samples. SID can be connected to a PC or via LAN using USB connectivity.
Fully implemented into the MAESTRO software, SID enables independent sample logging or fully integrated sample ID transfer to the data file with multiple user-defined options for sample verification and the handling of deviations.
The GERSTEL Cooled Agitator is a modified version of the standard 6 position agitator used with the MultiPurpose Autosampler. It incorporates a Peltier based cryostat that allows samples can be cooled down to 10C and is also useful when stable ambient temperature are required.
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.
Automated Filtration Using The MPS
Suspended particles and matrix material in a sample can significantly influence analysis results and system suitability. Removing particulate matter from a sample or extract prior to analysis is therefore critical for many GC/MS- and LC/MS analysis methods, particularly when large series of samples must be analyzed automatically.
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.
The GERSTEP MPS configured as Headspace Autosampler provides the analyst with a high productive tool for performing GC Headspace analysis. The MPS is perfectly suited for routine analysis for R&D applications that demand a higher degree flexibility.
GERSTEL provides a wide range of cooled trays and stacks for the MPS Robotic series either as part of an analysis system or as an off-line WorkStation. Trays and stacks available with Peltier cooling or cryostatic cooling covering a temperature range from 4 to 70C.
Water analysis can be complicated if the sample contains a large proportion of suspended substances and foreign particles.
Membrane extraction promises simplification in this case: a novel procedure for sample preparation developed by the Environmental Research Centre Leipzig-Halle, which has been automated by GERSTEL.
The MultiPurposeSamplers MPS are multi-functional autosamplers with a broad range of applications.
It combines the benefits of an MPS Robotic with those of an MPS Robotic Pro.
The multi-functional autosampler with a broad range of applications.
Fully automated solvent evaporation integrated with your sample preparation.
The GERSTEL Multi-Position Evaporation Station (mVAP) performs solvent evaporation enabling automated sample concentration for lower detection limits as well as solvent exchange for improved chromatography and LC/MS ionization. mVAP is an option for the GERSTEL MultiPurpose Sampler (MPS): Up to 196 samples in standard autosampler vials can be concentrated in batches of up to six.
quickMix for the GERSTEL MPS Robotic series enables extremely fast and efficient mixing nad extraction of samples as part of the automated sample preparation process.
The mixing power is comparable to that of vortex mixing. Samples are agitated in a special tray on the module, depending on the vial size holding up to 6 samples at a time. The tray can be exchanged to operate with 2 mL, 4 mL, 10 mL and 20 mL vials. If needed, quickMix can be configured with a heated tray.
Solid Phase Micro Extraction (SPME) is widely used technoque for extraction and concentration of VOCs and SVOCs combined with GC/MS. SPME is especially useful in the food, flavor and beverage industries and for environmental monitoring.
The MPS Robotic is a highly efficient GC/MS and LC/MS autosampler with extended robotic functionality. The MPS robotic provides reliable and efficient processing of complex tasks. Syringes are mounted in individual syringe modules, which be exchanged automatically within a running sequence when using the MPS RoboticPro for maximum flexibility.
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.
Standard autosampler vials are placed in the balanec by the MPS and liquid samples, stnadards, reagents or diluents added, weighed and registered separately. For each sample, mulitple liquid additions can be defined by mouse-click in the MAESTRO Software.
Flexible and reliable sample preparation robot providing efficient automation of your laboratory processes.
The GERSTEL MuliPurpose Sampler (MPS) provides a wide range of capabilities in one robotic system. The MPS WorkStation is a bench-top version of the MPS, independent of the GC/MS or LC/MS analysis system. The WorkStation can be configured as Single Head or Dual Head version enabling it to perform a range of functions to meet almost every requirements in terms of performance and throughput. The MPS WorkStation provides complete flexiblity. In combination with the GERSTEL MAESTRO software, the MPS WorkStation offers simple set-up and advanced automation capabilities.
