The AutoTrace workstation automates the cartridge or disk conditioning, sample loading, rinsing, and eluting steps for large volume aqueous solution extractions (20mL to 20L). The unit can process up to six samples in parallel, automatically conditioning, washing, and eluting SPE cartridges or disks with a choice of up to five reagents. The unit also segregates aqueous and solvent waste using separate waste lines for efficient, cost effective waste handling. The systems are designed to automate the cartridge or disk requirements for U.S. EPA water analysis methods.
Features
- Use SPE technology for liquid-liquid extraction
- Automated sample loading of liquids onto SPE cartridges
- Automated eluting of SPE cartridges with organic solvent
- Closed systems with a fan to vent solvent vapors
- Positive pressure loading and elution of samples and solvents
Benefits
- Reduced solvent usage and elimination of glassware
- Does not require technician involvement to maintain a reservoir of liquid in the SPE cartridge
- Does not require technician involvement to control the flow of organics solvent through the SPE cartridge
- No hood required
- Provides constant flow of liquids through SPE cartridges
