Spider C06 Fraction collector and injector
Unit for automatic injection and and fraction collection in preparative and flash chromatography
SPIDER allows automation of flash and preparative applications. It can be controlled using PC program, just as using PC keyboard.
SPIDER is connected to chromatographic system, which is controlled by program ECOMAC SW.
An input three-way solenoid valve is connected before pump. Solvent goes to the pump through valve B. For sample injection is the valve A switched on for a programmed time. The valve C is used for column washing.
An output six-way solenoid valve is connected to the detector output. Wanted fractions are collected by switching on of the various positions of the output six-way valve.
At the back panel connector are pins that can be switched on by the program ECOMAC. They can be used for control of next units, for example, for external valve switch on when column is washed.
Fraction selection is done by means of ECOMAC functions:
- control by means of time table
- control based on peak detection at chosen signal
SPIDER main features:
- Unit simplicity
- Easy programming of fraction collection
- Possibility to connect electronically controlled valve for a flow reversion when column is washed
- Valve position display
- Manual valves control from PC keyboard by developed method
