GC/GCMS Solution

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.

Description

Automated Solid Phase Extraction (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.

Disposable Pipette Extraction (DPX)

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.

Thermal Desorption Unit (TDU 2)

The worlds most flexible Thermal Desoprtion Instrument

The Thermal Desorption Unit (TDU 2) is a flexible automated solution for thermal desorption and thermal extraction. The TDU 2 fits on top of any modern GC without the need for additional bench space and it is perfectly suited for the analysis of gaseous, liquid and solid samples.

Twister® / Stir Bar Sorptive Extraction (SBSE)

The GERSTEL Twister® enables efficient extraction of organic compounds from aqueous matrices based on Stir Bar Sorptive Extraction (SBSE). SBSE is a solvent-free extraction technique, which is significantly faster than most conventional extraction techniques. SBSE is up to 1000x more sensitive than SPME since the stir bar has significantly more sorbent volume and since it can extract, and concentrate analytes from, a much larger sample volume due to the efficient stirring.

Olfactory Detection Port ODP

Parallel olfactory detection of GC fractions

The ODP sniff port allows the sensing of compounds by the human nose as they elute from the gas chromatograph. The effluent is split as it leaves the column so that it arrives simultaneously at the nose and at the detector.

This way additional information is gained on compounds that are responsible for specific odors.
