SPE-03
SPE-03 4-Channel Cleanup Station
SPE-03
4-channel cleanup station
is designed for automatic solid phase extraction of large volume water
samples. It has four pumps to handle four samples simultaneously. By providing constant flow rate and
well controlled elution procedures, SPE-03 helps to improve quality and efficiency of water analysis and
release chemists from tedious sample preparation routines.
1. Features
1.1 Easy operation
SPE-03 uses built-in methods for automatic extraction. The
methods can be easily edited and saved for repeated use.
The operation of instrument involves only 7 buttons.
Below are typical routine operation procedures:
•
Place sample inlet probes in samples
•
Place columns and receiving containers
•
Select method
•
Press start/stop button
1.2 Blockage detection and smart handling
The system can detect the blockage and reduce the flow
rate accordingly. If blockage still occurs at the minimum
flow rate, the instrument will pause and wait for human
attendance.
1.3 Built-in air pump for drying of SPE column
If the final analysis is by GC or GC-MS, the collected
fraction after SPE cleanup needs concentration. Moisture left in the fraction can affect the concentration
process. A drying step is necessary after loading the water sample to SPE column. This is normally
achieved by blowing air or nitrogen through the SPE column. SPE-03 has a built-in air pump and thus a
gas cylinder is not necessary.
1.4 Small footprint and computer-free operation
The instrument has a very small footprint and does not need a computer. The elution solvents are placed
on the top of the instrument. The compact design helps to save precious laboratory space.
1.5 Different flow rate for each elution steps
Different flow rates can be set for column conditioning, sample loading, and elution. Procedures that are
not sensitive to flow rate (e.g. conditioning and blow dry) can use higher flow rate to save time.
