Organic Sample Preparation
  • Description




Sepaths UP is designed for both cartridge and disk applications to treat samples with different volume. It can be applied to extract trace organic compounds from drinking water, surface water, ground water, food, beverage and other samples. Sepaths UP automatically treats from1 to 12 same or different samples, through the whole treatment process, including condition, sample loading, rinsing, elution and concentration. It is a closed system able to completely remove solvent vapours trough the included exhaust line.

SEPLINE-SSepLine-S automated solid phase extractor is the result of latest liquid-solid extraction techniques and mass chromatography highest requirements in terms of sensitivity and reproducibility. Largely used in environmental protection, food, petrochemical, pharmaceutical, clinical, life sciences and other applications thanks to its flexibility. SepLine-S series includes three models: Single, Dual and Four-channels. Condition, sample loading, rinsing and elution steps are processed automatically by software according to user needs. A unique low-pressure sealing technology accurately controls the liquid flow through the syringe and avoid cross contamination . Multi-channel mode improves the efficiency of the SPE method and guarantees reproducibility and stability of sample pre-treatment.

Liquid separation by air bubble

Thanks to air bubble , SepLine-S is able to avoid liquid mixing when two different solvents and/or samples flow into the liquid circuit. Advantages are:

to prevent polarity change
to improve sample recovery

Precise flow rate control

High precision syringes
High precision quantitative tubes to ensure accurate control of sample and solvent dispensing
Flow accuracy: 0.1%
Flowrate: from 0,1 to 100mL/min


Single channel AutoSPE system to perform single sample batch processing. It can automatically achieve conditioning, sample loading, rinsing and eluting steps. Thanks to the included nitrogen purge module, SepLine-S is the ideal partner for routine and R&D needs in the organic sample preparation. The new quantitative concentrator can be connected to the main unit by a plug-and-play procedure.


Dual channels AutoSPE system to perform simultaneously two samples. Management system allows running different methods for each channel.

Four channels AutoSPE system to perform simultaneously four samples, improving efficiency and productivity.
