SPE automation

Automated Solid Phase Extraction Elution Unit

The EL870 is a device that automates ”elution” in solid phase extraction, which is a chromatographic pretreatment method. ”Elution” is an important operation for high accuracy analysis.
The EL870 is equipped with a high-precision syringe pump that simultaneously improves efficiency and accuracy through automation.

To ensure a consistent recovery rate, the system includes a technique called ”soak mode”.
This mode automatically allows for a specific period of static standing during the dissolution process. After immersing the dissolution solvent and solid-phase filling agent for a set time, the system can perform a stable dissolution process at a constant flow rate.

Positive pressure elution
Accurate flow rate control
Soak mode gives better recovery rate
Any type of cartridge can be used


Automated SPE
A: The display and operation keys display the setting details, operation status, etc.Sets the method and initiates the operation.

B: Check valve controls suction and discharge into the syringe and prevents the backflow of solvent.
