HPLC chromatography detector S 4345

PDAUV/VIS

The S 4345 and S 4350 PDA - Detector are photodiode array (PDA) detectors for routine analysis and sophisticated research. The dual lamp design offers a wavelength range of 190 – 720 nm ( with 256 Diodes) or from 190 - 1015nm (with 1024 diodes) with a low baseline noise. The front accessible flow cell can easily be exchanged, as can be the lamps which are accessible through a side panel in the instrument housing.S 4345/ S 4350 PDA (DAD) HPLC Detector Schambeck SFD 4-Channel UV/Vis - Detector The S 4345 / S 4350 PDA - Detector features 4-Wavelength channels to measure chromatograms at 4 different wavelengths at the same time. With this feature the optimum wavelength can be selected for each analysed substance. Integrated Peak Detector The integrated Peak Detector works as a basic fraction collector. The peak detection level can be freely programmed for peak start and peak end to enhance the collection purity. An integrated 24V output for switching a solenoid valve is used for the fraction collection, which is automatically operated with a selectable time delay. Optional - Analog Output The S 4345 / S 4350 PDA - Detector are available with an optional 4-Channel Analog output. This D/A converter output option is offered to keep the system flexible to be used with any data acquisition software available.
