Four wavelengths simultaneously in one cell, continuous scan 200 - 400 nm. External cell. Standard power supply.
- Description
- Parameters
Flash 12 DAD is a 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 the detector be used also for analytical purpose. Noise level at 254 nm is ± 8 x 10-5 AU with short-connected 1m long fiber optics cable (optical cable).
The unit is designed as stand alone with 90-264 V power supply and RS232 controlling. It is derived from OEM built-in unit with powering 24-36 V DC.
The unit’s DAD (diode array detector) design offers many advantages:
- continuous 5Hz scan or absorbance measuring on four wavelengths simultaneously
- wavelength setting from 200 up to 400 nm in increments of 1 nm
- lamp work hours are counted using the built-in counter
- Clarity PDA module support for 3D measurement
- allows external cell connection by using fiber optic cables
- unit is controlled by RS232 interface
Cell is installed out of the unit and it is connected to the unit using fiber optic cable with SMA connectors. External cells and fiber optics cables are a subject of customers' choice and therefore are not included in price of detector.
