全自动固相萃取英文介绍
Introduction of Automated solid-phase extraction system
Equipment name: Automated solid-phase extraction system
Equipment Type: J2 Scientific SPEi Inline SPE
Equipment Function: It is mainly used for sample pre-treatment,including food、agricultural 、animal and plant samples、aquatic products and the environment(soil,water,etc).Currently,it is used in the pre-pre-treatment of pesticide residues in Chinese herbal medicines.
Equipment Key Technical Parameter:
The PrepLinc SPEi from J2 Scientific accentuates our line of full-featured automated sample preparation instruments. Use the SPEi as a stand-alone automated SPE system or integrate with our AccuVap Evaporation Systems for complete sample prep.
1、Standout Features.
+ Use cartridges from 1mL - 15mL plus many specialty and flash chromatography columns + Perform multi-column procedures; up to 3 columns inline
+ Concentrate eluate to final volume or concentrate between prep processes with our AccuVap + Ability to perform reverse elution through cartridge for special applications
+ Unlimited elution volumes
2、Exceptional hardware & software features make the PrepLinc SPEi an integral part of your prep lab.
+ Positive Pressure Elution for Sample and Solvents
+ Programmable Flowrates to 60 mls/min
+ Nitrogen Drying
+ Select from 12 Solvents for processing(3 standard)
+ Closed System
+ Pressure Monitoring
+ Customizable trays & autosampler mat
+ Add up to 5 SPE column modules
3、Method Operations
The SPE method is created by choosing and defining operations in the order they should occur. The available operations are as follows:
Drying/Clear: clears lines of solvent
Probe Rinse: forces an external rinse of the probe
Mixing: use the syringe pump to mix sample in vial
Condition: choose solvent, volume and rate of conditioning solvent through column
Dilution: dilute sample in tube prior to injection
Prime: prime all tubing lines with solvent of choice
Sample Introduction: moves sample completely onto column
Rinse Direct Inject Port: cleans port between injections
Sample Injection: pickup volume of sample from vial
Flow Path Rinse: rinse sample flow path between samples.
Wait/Soak: programmable time that sample held on column with no flow.
Elution: choose solvent, volume and rate of elution solvent through column into collection vial or to another device for
further processing (ie. AccuVap).
Wash: choose solvent, volume and rate of wash solvent through the column to remove interferrences.
N2 Purge: use nitrogen to purge solvent lines.
