ECOM COMPACT PREPARATIVE SYSTEM (250 ml/min, ECS28)

A highly effective Compact semi-preparative system containing UV-VIS DAD detector, 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 entire spectrum.

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

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 up to 10 ml/min and a fraction collector.

Main parts

TOY18DAD800L DETECTOR

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.

ECF2096 FRACTION COLLECTOR

Fractions are collected according to 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.

AUTOMATIC INJECT VALVE

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

SYSTEM PC INFO

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. 

ECP2200 PREPARATIVE GRADIENT PUMP

Modified for the compact system, quaternary gradient pumps 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.
