Four wavelengths simultaneously,
scan of whole spectrum 200 - 600 nm
Flash 06S DAD 600 is an UV diode array detector, which allows measuring absorbance of four wavelengths simultaneously in one cell just as measuring of whole spectrum (scan). This unit is used in liquid chromatography to verify analyzed samples by means of four wavelengths or in situations when some peaks absorb on different wavelengths. It is possible to use the detector in flash and preparative applications. By using analytical cell can be detector used also for analytical purpose. Noise level at 254 nm is ± 5 x 10-5 AU with a test cell.
The unit is designed as stand alone with 90–264 V power supply and RS232 controlling. It is derived from OEM build-in unit with powering 24-36 V DC.
