Flash 06 DAD 400 Detector
Four wavelengths simultaneously,
scan of whole spectrum 200 - 400 nm
Flash 06 DAD 400 is an OEM build-in type of 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 build in unit with 24-36V power supply and RS232 controlling. On request can be sold in classical case with 90-264 V powering.
The unit’s DAD (diode array detector) design offers many advantages:
- wavelength setting from 200 up to 400 nm in increments of 1nm
- absorbance measuring on four wavelengths simultaneously
- scan of whole spectrum is possible in each time
- lamp work hours are counted using the built-in counter
- the cell is easy to replace from the side of the detector
- powering by 24V
- unit is controlled by RS232 interface
