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.
The GERSTEL CTS is used for cryogenic trapping and concentration of analytes. The CTS enables improved separation and lower detection limits. Following the concentration step, analytes are introduced to the GC column using a highly accurate temperature program. The CTS can be used in a single-column GC system placed at the head of the column or between the pre-column and the analytical column in a multidimensional system in order to refocus analytes prior to analytical separation.
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 GRAPHPACK technology was designed to provide leak-free, low dead volume, inert connections quickly and reliably for any type of connection used for gas chromatography. The same technology is used for inlet and detector connections as well as for column connections (with or without make-up gas) and multiple column splitters. GRAPHPACK fittings exist for almost all GC inlets and detectors, so a laboratory with multiple brands of GCs can use the same ferrules, adapters, and nut for all connections needs.
In LC/MS, we work hard to reach the goal of achieving the perfect LC separation and combining it with the most efficient ionization and lowest achievable MS detection limits for our analytes.
The LC separation may require a certain pH and polarity range of the eluent, while analyte ionization in the LC/MS ionization source requires yet another pH, a different buffer – or even derivatization of the analyte for best possible efficiency or optimized spectral information. How to optimize both? The logical answer is to take the effluent from the perfect LC separation and optimize it for MS analysis.
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 GERSTEL Olfactory Data Interpreter (ODI) enables fast and reliable evaluation of olfactory information including identification of unknown odor-active compounds. Chromatography data is typically acquired using a mass spectrometer / mass selective detector (MSD), a Flame Ionization Detector (FID) or a Sulfur Chemiluminescence Dectector (SCD) or a combination thereof. The chromatogram is loaded into the ODI software, which automatically recognizes the chromatogram data format before importing the data. In parallel, an olfactogram is imported with information provided by the user as he or she assessed odors eluting from the GC column in parallel with the detection process during the GC run. The olfactogram combines spoken comments from the sensory analyst and the registered intensities along a time axis. The „Olfactory Intensity Device“ (OID) conveniently enables the user to indicate the intensity of the olfactory impression as it transpires. Text comments are added using voice recognition software to translate spoken descriptors. The combined information is presented in the ODI-Software in a clear and concise overview including a chromatogram, an olfactogram and a table.

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.
Gas chromatography (GC) experts rely on sharp peaks and baseline resolution to provide accurate answers. To perform chromatographic analysis of real-world samples, analysts often must deal with either complex sample types such as essential oils and petroleum fractions, or complex matrices like biological fluids, foods, sludge, or polymers. Once the sample has been prepared for analysis, separation of all the individual compounds present by means of a single chromatographic separation can be challenging due to the compounds having different ranges of polarity, boiling point, solubility, MW, and concentration. It is therefore necessary to use innovative yet robust techniques that go beyond using a single chromatographic dimension to achieve compound separation.
