Sample Preparation
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
Configuration:
 |
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. C: Syringe A glass syringe with a capacity of 5 mL can be attached. |
It is usable with any shape of solid-phase column.
