Automation of solid phase extraction for pesticide residue and environmental analysis

 Below are 2 types of automatic solid phase extraction instruments targeting different application fields. SPE-01 plus is designed for analysis of pesticide 
and drug residues in food samples. SPE-03 is designed for solid phase extraction of water samples.

 

SPE-01 Cleanup Station

SPE-01 plus Cleanup Station


SPE-03 4-channel Cleanup Station

Common features

1) Full automation

Use methods and sequence to automate all the procedures for the cleanup. A typical method will first condition the column, and then load sample  to the column. 
Several steps of elution using different solvents are followed and target fractions are collected for instrumental determination. The instruments can store up to 3 
methods for handling different samples or for cleaning system to avoid cross contamination.

2) Small footprint and computer-free operation  

The instrument has a small footprint and does not need computer. It helps to save precious laboratory space. When volatile or toxic solvents (such as hexane, acetone, and petroleum ether) are used, the instrument can be conveniently place in a fume hood.

3) Column blockage detection

The instrument can automatically detect the column blockage and reduce the flow rate accordingly or  pause the process.
