AquaTrace ASPE900

GL Sciences · Sample preparation

From the water sample to the concentrated extract.

This stand-alone system prepares tap water, drinking water and groundwater for subsequent chromatographic analysis. Automated processing reduces repetitive manual extraction work. A valveless piston pump delivers samples and solvents while flow paths are switched under method control.

• Process up to six samples in parallel
• Automate the extraction workflow including evaporation
• Set up methods and monitor progress on the colour touchscreen
• Store up to 120 methods on the instrument and 120 on USB memory
• Use up to seven solvent positions for flexible workflows
• Use Luer-connected cartridges; 6 mL syringe-barrel format as standard

Automated workflow

Six steps in one system.

1. Conditioning

   Prepare the selected cartridge with the solvents specified by the method.

2. Sample loading

   Pass water through the sorbent at a controlled flow to retain target compounds.

3. Rinsing

   Remove interfering matrix components with a suitable rinse step.

4. Drying

   Remove residual water by suction, nitrogen purging or a combination of both.

5. Elution

   Transfer retained compounds into collection tubes using the selected solvent.

6. Evaporation

   Concentrate the eluate inside the instrument with nitrogen and optional heating in an aluminium block at 30 to 60 °C.

Operation and documentation

From loading to the finished extract.

After loading samples, cartridges and solvents, select a stored method. Individual lines can be selected and a timer defines the start and end of operation. The screen shows process progress and remaining time. Edited parameters can be saved and the calculated total duration is updated.

The ASSISTANT PC application supports method editing, transfer and documentation. Reports combine an automatically generated flow diagram with settings and user notes such as cartridge type, batch or sampling location. Logs record operation and maintenance; reports can be printed or saved as PDF. The email function requires a PC with an internet connection.

Concentrate and clean

Graduated GL-SPE tubes allow concentration directly in the system. Nitrogen is directed at an angle onto the tube wall. An optional liquid-level sensor stops nitrogen delivery at a selected final volume between 0.1 and 5 mL. The usable range depends on the equipment and method.

Sample lines can be rinsed with organic solvents, including toluene. Suitable rinsing steps help reduce carryover between samples. Cartridge, solvent, sample matrix and target compounds must be selected together for the method.

Advice and integration
