Kompaktowy system preparatywny (50 ml/min)
Wysokosprawny, praparatywny system HPLC zawiera detektor DAD UV-VIS, preparatywną pompę gradientową, automatyczny nawór nastrzykowy oraz kolektor frakcji. Detktor umożliwia pomiar absorbancji przy czterech długościach fali w tym samym momencie lub skanowanie w całym spektrum.
System kontrolowany jest za pomocą wbudowanego komputera z ekranem dotykowym
Modułowa konstrukcja pozwala skonfigurować jednostkę pod potrzeby klienta. System posiada detektor z długością fali w zakresie 200 - 800 nm, pompę z przepływem do 50 ml/min oraz kolektor frakcji.
Główne komponenty
It is UV-VIS diode array detector, which allow measuring absorbance of four wavelengths in 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 chosen method, which is simply created using touch screen. Racks for 8, 21, 40 ml tubes.
Valve is driven by a stepmotor and it is automatically switched by software. System also allows manual sample injection by opened column.
Installed industrial PC with Intel Atom 4 core processor. OS Linux, Touch screen 12,1“ 1024 x 786, SW QUEEN controlls: gradient, flow rate, wavelengths, fractions collection etc. Remote administration is available.
Modified for compact system, quaternary gradient pumps with flow rate up to 50 ml/min (30 MPa, 4351 PSI). Unit software includes new learning algorithm for pulsation suppression and many testing and diagnostic functions.
