DTS-240 Fully Automatic Solid Phase Extraction System
Product Overview
The DTS-240 Fully Automatic Solid Phase Extraction System is an intelligent laboratory instrument developed for automated sample preparation before organic analysis. It performs the complete Solid Phase Extraction (SPE) workflow without operator intervention, including cartridge conditioning, sample loading, washing, drying, elution, and automatic cartridge switching.
Designed for continuous unattended operation, the DTS-240 processes up to 24 samples per batch, significantly improving laboratory efficiency while reducing manual labor, solvent exposure, and cross-contamination risks. The system is widely used in food safety laboratories, environmental monitoring, pharmaceutical research, agricultural residue analysis, water quality testing, commodity inspection, and chemical laboratories.

Key Features
●Fully automates the complete SPE process including conditioning, loading, washing, drying, elution, and cartridge switching.
●Standard dual-channel operation enables simultaneous conditioning, loading, drying, and elution; expandable to 4, 6, or 8 channels.
●Processes up to 24 samples continuously without manual intervention.
●Enclosed design minimizes laboratory contamination and prevents solvent exposure.
●Unique cartridge plunger technology maintains constant flow through the SPE cartridge for excellent recovery and reproducibility.
●Tool-free replacement of cartridge plungers for different cartridge sizes.
●Automatic plunger cleaning, sampling needle cleaning (inside and outside), and active waste discharge.
●Large integrated touchscreen with standalone operation, built-in method editor, wireless control, and intelligent method error reminders.

Working Principle
The DTS-240 automates Solid Phase Extraction by precisely controlling solvent delivery, sample loading, cartridge switching, waste removal, and nitrogen drying.
The instrument executes the programmed SPE sequence automatically:
1.Cartridge conditioning
2.Sample loading
3.Cartridge washing
4.Cartridge drying with nitrogen
5.Target analyte elution
6.Automatic waste separation
7.Sample collection
Its precision-controlled flow system ensures that the programmed flow rate is identical to the actual flow passing through the SPE cartridge, delivering high recovery rates and outstanding analytical reproducibility.
