High Performance Solvent Extractor

 HPSE Gemini High Performance Solvent Extractor

HPSE® Gemini is the sample preparation instrument which features new high performance solvent extraction technologies, and designed and developed by LabTech, Inc. It applies liquid solvents to extract target compounds from solid or semi-solid samples at high temperature and high pressure, which can increase the extraction speed and compounds recovering efficiency. In addition, it integrates online sample concentration and solid phase extraction module into one station, which supports one-stop operation from extractives to final purified samples. It also relieves analysts from the drudgery of sample preparation, so they can put more efforts on sample analysis.


Technical Features

Flexible model design Three models of HPSE® Gemini, Gemini-EV and Gemini-E.

Multiple-choice connection interface Support different connection ports as one computer.

Large sample range 1~100ml Optional vessels selection: 10ml, 22ml, 34ml, 66ml, 80ml, 100ml.

Three Key Functional Modules

High Pressure Extraction

  • Dual extraction channels can work simultaneously or individually.

  • 8 different extraction vessels for option, the system can work with different vessels simultaneously.

  • Self-sealing extraction vessels, easy operation.

  • Extraction at heating high temperature.

  • Convenient maintenance for seal replacement and path cleaning to eliminate the interference.


On-line Concentration

  • Trinity of vacuum, heating and nitrogen blowing technique.

  • Surrounded uniform heating.

  • Adjustable end point.

  • High pressure pump ensure the accuracy of solvent volume.

  • Automatically spray rinsing, cleaning, constant volume and solvent exchange.

  • Support to exchange 3 different solvents.

  • Liquid level sensor is not effected by solvent color.


Solid Phase Extraction

  • Ceramic syringe pump for the adjustable flow rate.

  • Support 1ml, 3ml, 6ml SPE cartridges.

  • Separate liquid paths ensure no cross contamination.

  • Fractionation collection can be separately but simultaneously in two channels.


Key extraction compounds: PCBs, insecticide, herbicide, dioxins and furans, specific heavy metal pollutants, petroleum hydrocarbons, PAH, pesticide residues, antibiotics, residues of veterinary drugs, arsenic, bromide compounds, Active ingredients in natural products, pharmaceutical additives in health supplement, pharmaceutical and food packaging materials, etc.


Fields: Environment, Food and Feed, Natural and Pharmaceutical Products, Petrochemical/Plastic/Polymers, Chinese medicines, Packing materials, Health care products, Disease control, Forensic and Security, etc.
