4 channel Scanning 200-400 200-800 250ml/min 30MPa

A highly effective compact preparative system containing a UV-VIS DAD detector, a preparative gradient pump, an automatic inject valve, and a fraction collector. The detector allows absorbance measuring at four wavelengths at the same time or scanning through the entire spectrum.

ECOM spol. s r.o.
Part number

The system is controlled by a built-in PC and touch screen.

A modular solution allows configuring the unit according to customer needs. This system contains a detector with a wavelength range of 200–800 nm, a pump with a flow rate of up to 250 ml/min, and a fraction collector.

Main parts

It is a UV-VIS diode array detector, which allows measuring the absorbance of four wavelengths in a range of 200–800 nm simultaneously in one cell just as scanning of whole spectra. Standardly is assembled with preparative cell PLCC07L, but other cells are available.

Fractions are collected according to the chosen method, which is simply created using a touch screen. Racks for 8, 21,40 ml tubes, 60 ml vials, or 12 funnels, 30 mm.

The valve is driven by a step motor and it is automatically switched by software. The system also allows manual sample injection by opening a column.

Installed industrial PC with Intel Atom 4 core processor. OS Linux, Touch screen 12,1“ 1024 x 786, SW QUEEN controls gradient, flow rate, wavelengths, fractions collection, etc. Remote administration is available. Possibility of measuring at four wavelengths at the same time or scanning through entire spectra. Furthermore, the possibility of displaying 3D data.

Modified for the compact system, quaternary gradient pump with flow rate up to 250 ml/min (30 MPa at 100 ml/min and then linearly down up to 15 MPa at 250 ml/min). Unit software includes a new learning algorithm for pulsation suppression and many testing and diagnostic functions.
