LCD 2073A Dual UV Detector
is a new type of UV detector, which allows measuring absorbance of two wavelengths simultaneously in one cell. This unit is used in liquid chromatography to verify analyzed samples by means of a second wavelength or in situations when some peaks absorb on different wavelengths. It is possible to use the detector in analytical, preparative or flash applications by using different cells. Noise level at 254 nm is ± 1 x 10-4 AU with an empty cell.
The unit’s DAD (diode array detector) design offers many advantages:
- A wavelength setting may be changed in steps of 1nm
- The unit is easy for operating, reference and sample signal are available for detector diagnostics
- Output signal is it available in digital and analogue form on the output connector
- Work hours of lamp are counted using build in counter.
- Detector cell is easy replaceable from the side of the detector
- it is possible to control the unit using the external logic signals or an RS232 interface
This unit is an OEM aplication of TOPAZ Dual UV Detector
